Gateron Optical Switches – The fastest Switches for gaming!
Optical switches are much more durable than conventional mechanical keyboard switches and are rated for 100 million keystrokes.
They have a high actuation point of 1.5mm for fast response. Light Strike optical switches utilize a horizontal infrared beam which is transmitted across the width of the inner keyswitch.
The infrared beam is normally blocked from reaching a sensor across from it by the stem. Once a switch is pressed, the switch stem no longer blocks the infrared beam and the beam is detected by the sensor, which activates the switch.
Due to the optical mechanism, an optical switch has an extremely fast response time of 0.2ms, which means faster reactions in those times where timing is critical, such as when gaming.

Keyboard was amazing! Was trying out a pre-built to see how it was (after not using a pre-built for a good few years), and the gk61 was surprisingly good! 100% reccomened to anyone who wants to try out pre-builds or just anyone who is looking for the best keyboard apart from a few, and the price for this keyboard i’d personally say is way under!
I bought this keyboard for the purpose of modding it, replacing the switches and keycaps etc. I ordered the silent brown switches even though I was going to replace them with jelly blacks. The silent browns had a good tactility however were very scratchy and not my personal liking. However, the quality and build of the board and PCB itself is excellent and was perfect for my needs since I was replacing the switches anyway. I paid 60 on offer for this keyboard and for that price it was 100% worth it. The RGB LEDs are bright and the software is ok but if you’re looking for a keyboard to mod this is the one for you!
Pues llevo como 5 meses, para esta review considero que se mantiene todava en su rango de precio establecido, lo nico que me aqueja era que no lo poda comprar en switches amarillos y pues que la caja me llego puteada, nada serio pero pues aun as lo menciono para que no se asusten si llega el suyo as.
Ahora, me toco llevarme el de switches brown por que ocupo que sea mas “silencioso” que los blue o red, sirve muy muy muy bien estos switches para escrituras largas, y pues para gustos, colores, puedes llevarte de un tipo de switch y pedir otros de la misma marca para personalizarlo.
Recomiendo este teclado para que le hagas pequeas modificaciones, como lubricar los switches , ponerle O rings, tiene un compartimento para una batera para ser un teclado BT, pero para mi, ah lo dejo, ojo que apenas se notara el uso de las teclas o space-bar por el tipo de plstico, as que igual por dejarle algo mas puedes comprar keycaps que le Queden de Pbt y hacer que se sienta mejor.
Es una buena “base” en mi criterio, se presta a mucho y es en general uno de los teclados de gama media que recomiendo yo.
Lights up nice works great fantastic so happy with this
The keyboard is the best I’ve ever used the keys feel great and the keyboard fits any setup I do wish the software had more options but noticing time can’t fix
This keyboard is just amazing I am using it for about 6 months now and it’s great everything works perfectly I have no complaints with it what so eve

This keyboard is alright, I guess a semi alternative version of the huntsman mini if you want something close to being as responsive as it, it didn’t live up to the standards I got put in my head after hearing reviews on responsiveness. Also, The Cheap keycaps hitting the plastic board is flat out annoying, but eh it is what it is and just like with all keyboards you can lube the switches and sound dampen it for better sound after all of that it is so bad after all. I just wouldn’t recommend maining this keyboard when there’s way for potential out there
I brought for my daughter, she says it’s very responsive and has a quality build.
It’s a really nice keyboard, especially if you are new to mechanical keyboards, I recommend getting a set of keycaps like I did, the stock ones aren’t as good as some other ones you can get, overall great keyboard
Affordable price, everything as described, trouble-free installation. Everything’s all righ

I liked it and it felt very good, but when trying to be on calls it could be annoying or if I was playing games where you hit the keys alot, it could be very loud and it would be hard to hear the game.
Ive had this keyboard for over a year now and nothing has gone wrong its relieable and feels great, my only problem are the screws be careful they strip easy.

This Keyboard Is Very Good Gor The Price It Is Okay And It Is Good At Typing And Gaming, The Switches Feel Good And Smooth, This Keyboard Is Not Height Adjustable But Angle They Give Is Good And Isn’t Annoying But This Could Be Different To Other People. My Biggest Problem Is That The RGB Software Is Terrible And Not Good At All It Is Very Basic And For The Price You Are Paying This Is Something Basic You Would Expect So Do Not Buy This. Instead Buy A GK61 From The Brand Epomaker Skyloong As It Is The Same Keyboard But With Good RGB Software And Quite Literally The Same Keyboard As This One But Just With Different Switches (Maybe)
And Better RGB Software And That Keyboard Can Be Found On Their Website Or Amazon. This Keyboard Would Have Been Better If It Had Better RGB Software Or If It Had A Lower Price.
Check the video I submitted as I show how the program works and my favourite settings. Absolutely nothing I’d change about it. High quality with a nice click, perfect colour and simply to use. I got the UK one but it also comes in DE and US.
To get the software on Windows search “www.hk-gaming.com” and the second website titled “download” from there select in the GK61 column, “S/N Starting with: GK61US” (you can change it to UK by doing what I show in the video, changing what different keys mean). Click “download (v1.1_0113)” and name it + put it in your files. Once downloaded open the file and it will bring you to Microsoft store where you press “install anyway” It will ask you for your pin, it’s completely safe don’t worry. Type in your pin and once it loads it will ask you for your preferred language. And in this order press “next, choose where the file goes, next, name the file, next, install, finish” open the program and from there I show you in the video.
Hope this helps! Byeeee

Pretty good gaming wise, bad stabilizers and also very very loud. If you don’t really care and just need a good gaming keyboard it’s definitely the way to go. I’m getting the Durock plate mount stabs to help with the problems.
Love the keyboard and the software it really nice it doesn’t move while gaming also has really good click response excellent for the price you pay But the box doesn’t give you the software name to download it so you have to find it yourself it already comes with a keycap puller and a switch puller the switches I got where mechanical blue switches and the hey caps fell good but can be better I love this keyboard over all I’ll give it a 9/10
Great to the touch right size for gaming Great value
This is my first gaming keyboard and I love it. The lavender color is super pretty and the different lighting modes are fantastic. It feels very sturdy and like good quality. The keys feel fine, some people are saying the key caps aren’t good but I honestly don’t know why as they sound and feel good to me. The only bad thing about this keyboard is it is very slightly uneven at the bottom so it wobbles a little bit, you might have to put a piece of electrical tape or something there to fix it but that’s not a big problem at all, just kind of annoying. I highly recommend this
Great product, my son is very particular and he is very happy with i

Bought for my 11 year old to use in conjunction with his Xbox. It is perfect, good size and very hard wearing considering how vigorously the keys are used! According to him it’s easy to use and set up. It was a good buy and reasonable price!
Bought for my son to replace his disastrous first choice and this one has stood up well to many hours of gaming. Very pleased.
This keyboard is a great option for anyone looking to get a mechanical keyboard, it is a great option for its price tag. It is also a 60% board which is great because it takes up less desk space while it still has the crucial arrow keys.

spacebar is the best bit. The thoccy sound does not make me regret buying this at all.

This keyboard is so impressive, very quiet key tap and the colour changes are excellent, very pleased.
Es muy bueno la verdad recomendado de 10, me ha mostrado que es de muy buena calidad, y pues los colores y todo son grandiosos, el tamao igual es bueno, lo nico que me afect pero no creo que sea malo es que una vez jugando fortnite, como que haca intervencin osea olyna tecla estaba presionada, pero creo que pudo haber sido polvo ya que despus de una limpiada todo se solucio
his is a great affordable hot swap keyboard for anyone trying to get into the stressful, depraved, and wonderful world of customizable mechanical keyboards. when i first got this keyboard the stock switch and keycaps sounded not so great (gateron mech blacks), but after 6 back breaking soul crushing hours i finally got all 61 switches lubed and back into the pcb with new pbt keycaps. i would also recommend modding the stabs on this board because the stock sound is super rattly. all in all though this is a great board and it shipped really fast, 10/10 would recommend.
Seems to be standing up to the point of the children, good gaming keyboard

HOWEVER, one word of warning – it’s a US layout. No sign key and the @ symbol is Shift+2, not Shift+’. Honestly though, for me this isn’t that much of a big deal. It actually still inputs as a sign even when I press Shift+3, and I’m kind of used to the swapped @ placement due to using Macs throughout my life. There is no # key anywhere so that may be an issue for some. I also had to play around in the HK gaming keyboard software to get the Up arrow to only input as / so that I could still type a question mark. Not a huge deal though and I just swapped Up to Right Shift in the software – it’s next to it anyway
As my first mechanical keyboard I am genuinely over the moon with it – the quality is great. There’s a tiny bit of metal ringing sound when you type (especially using the spacebar) but I don’t mind this. The RGB lighting is nice and has a good amount of different settings/colours to choose from. I would honestly rate 5 stars if I had actually received a UK layout, but consider my rating a 4.5.
Es un buen teclado relacin calidad precio, todo bien en general, es un buen teclado y cumple con todas las funciones de un teclado normal.
Las nicas contras por decirlo de alguna manera es que
1 aunque no tengan un sonido clicky las keycaps hacen mucho ruido al momento de pulsar la tecla
2 Al pasar de un tiempo los recorridos se sienten un poco arenosos haciendo que al momento de usar, ms que nada de jugar resulta un poco incomodo pero nada para decirle no a este teclado.
Really good for a budget keyboard. I love clicky switches and it’s just so satisfying.
Really good for a budget keyboard. I love clicky switches and it’s just so satisfying.
EDIT:
I finally got around to modding this keyboard and man oh man… I love it, so happy with the quality I was able to get out of this budget board! It sounds better than a lot of $300+ keyboards I’ve heard. 5/5 would recommend, although the stabilizers 100% need the hole mod to sounds good!
I got the gk61 with black switches, which aren’t suppose to feel clicky, and I really like them. Only thing I really don’t like is the stabs, which aren’t the best, but aren’t the worst either. Other than that the build quality is nice, and if you want to be able to use other switches than optical, make sure to get the mechanical switches, not the optical.
I got the yellow mechanical switches and I love them! Overall this keyboard is very good for the price. Only downside is that the space bar has a very bad rattle and sound, need to mod to fix.
This keyboard is amazing, I love the sound of the keyboard have, and it’s a pretty fast. I used to gaming, and this keyboard pretty good for gaming.

Perfect in every way, takes a little getting used to but it’s a perfect gaming keyboard for anyone looking for a good budget mechanical keyboard this is the 1.
Just been a day since I’ve been using it, but its an amazing product! Response time for a click is very high and the RGB lights work flawlessly. Would recommend the red one for anyone interested in gaming!
I am used to fullsize keyboards and have been looking for a purple keyboard with RGB leds for the LONGEST time. When I found this one, I figured I would get used to the smaller layout of the keyboard, but I received it and just hated it. With pain in my heart, I returned it.
If you like small keyboard layouts, I recommend this product 100% which is why I’m writing this review. It’s just not for me. The RGB leds were absolutely gorgeous and the keyboard overall felt very nice and durable when testing it out. The colour lavender it has is absolutely perfect.
All in all, if this keyboard existed in fullsize layout I would absolutely THROW my money at it because it’s exactly what I’ve been looking for. But I just can’t with the small layout. So sad 🙁
This keyboard is a really good option for a budget 60%. The optical gateron switches feel great (I got blacks) and the stabs are alright but the spacebar rattles a bit. It has plenty of good preset lighting modes and the rgb is really bright. You can also download a lighting software but I ended up not using it as the presets were better. I also customized it with custom keycaps (last pictures) and I plan to foam mod it and lube the switches.
I have had this keyboard for about 5 months and it still works perfectly with no problems at all. I would really recommend this to anyone.
Bought for my son which he loves. He says it’s an excellent gaming Keyboard

1) Responsive. 2) Deskspace. 3) Customizable
I bought the Malibu version of the GK61 with the yellow gateron switches and they are super responsive to touch. It seems like you can blow on the keys and they could type lol. The very responsive yellows could be a turn off to people who don’t like sensitive keys but I also have the blue switches so they are a great option as well. The yellow switches definitely give me an advantage for fast response games like COD and Fortnite.
As an artist and a student I need a lot of space on my desk and full sized keyboards took a lot of that space. With the Gk 61 I free up so much space and I can store it in a little drawer. If you’re looking for a 60% keyboard to free up your desk space and provide a great gaming experience this is the keyboard for you.
In these picture I show how the Gk 61 can be customized. Very cheap to customize along with an already budget friendly keyboard means that you have more bang for your buck!
This keyboard is brilliant for the price and the red switches sound really nice. The keys stabilizers are also really good its just the spacebar that needs a little improvement otherwise the keyboard is great.
Used it for 2 months and then spilled a drink on it. It never worked agai

I am happy with Gk61 and I am glad that my choice was the silver switch which is still fast for me just need time but the keyboard is good and I don’t feel eny different between this one and some of the big and expensive brands in the market.
They keyboard itself is spectacular! Works great, looks good. However, I just got this keyboard yesterday afternoon and as I was using it today I noticed how dirty the keycaps were, and I can garuntee the marks are not from my use as ive only used it a couple hours since receiving the keyboard. Not sure if any other buyers have had this issue, its easily fixable with a good cleaning of the keycaps. Just letting future buyers be aware of this issue.
Its a good keyboard and it also looks nice i got the red color and the lights are fine.
My son loves this small keyboard.. Plays various games on his gaming pc.. And says the keys respond well

Easy to set up and had a wide variety of light options, keys feel very nice!

Very high quality keyboard for the price. I got mine with the gateron reds and the feeling is amazing. The size of they keyboard gets some getting used to. Mainly missing the arrow keys but makes up for the quality and feel and the space it frees up. Only downside now it’s a US layout but I’m sure I gat get some keys for a UK keyboard somewhere
Lovely keyboard though!
My 15 year old loves it. Small and responsive, it’s what he hoped it would be like.

This is the review you have been looking for!
I have recently switched from an Apple’s wired keyboard to my very first mechanical keyboard. Here is my experience.
General observations:
– Since my old keyboard was low profile and was a membrane keyboard, I needed a bit of practice to get used to the feel.
– This is more personal, but it is quite a bit noisier than a membrane keyboard. Even if I bought the Gateron red switches version, you can hear me type from across the house. (To fix this issue, I will be trying o-rings soon and update this review with some statistics.)
UPDATE! The o-rings helped reduce the noise from the keycap’s plastic hitting the switch. It won’t make a huge difference, but it’s better than nothing when using mechanical keyboards at night.
– Probably the best entry-level mechanical keyboard there is on the market.
Pros:
– This 60 % keyboard still has all the keys you might need on a normal full-size keyboard. You can access these keys using the fn key or lock them by pressing on fn + q/w/e/r. You will have access to the arrow keys, the f1 to f12 keys and the other 9 keys that no one ever uses (insert, delete, page-up, page-down, home, etc). You will NOT have a numpad, although I am pretty sure you can add one through their software. Using a Mac and/or worried about medias keys? You can install Karabiner, which is a software used to remap your keys! I personally switched the Windows key with the left Alt and set my function keys to allow me to change my volume and play or pause my videos using fn + f(something).
– The switches are hot-swappable. You can remove them and replace them with any Gateron switches! I have not tried with other brands (because I do not own any other switches), but the manufacturer said Kalih switches will not work on this keyboard.
– It has an IP rating of 64 for water resistance. That means it is protected from total dust ingress and water spray from any direction.
– The way they curved their keys increases my typing accuracy and comfort.
– Very little wobble on the keys and it will not impede your typing.
– The RGB looks great!
– Small, portable (you can unplug the cable), not too heavy and quite solid. I was not able to twist it.
– It won’t slide on your desk and you can reposition it easily too.
Cons:
– While gaming, the edge (facing my way) on the space bar hurts my thumb. I think a slightly curved edge would offer better ergonomics.
– There is a microphone somewhere under the spacebar for one of the lightning setting. I DO NOT know if it can be used for spying, but I would personally rather remove it. I will be attempting to disassemble the keyboard and check the PCB if it’s easily removeable or if desoldering is required. (I will update this review once it’s done!) THIS MICROPHONE IS NOT MEANT TO RECORD AUDIO. IT IS ONLY FOR THE LIGHTNING EFFECT.
UPDATE! The microphone is round and soldered to the board. You can either desolder it to remove it, but I do not know if it will break the keyboard or not. I don’t have a desoldering kit, so I cannot attempt that. Instead, I decided to cover it with hot glue. It probably won’t prevent my fbi friend from listening to me, but at least, the sound will be muffled. 😉
– When removing the keys using the keycaps puller tool provided, it scratches the glossy sides. Also, it will dent the base of the keycaps. I would personally suggest using a wire keycaps puller.
UPDATE! While installing my o-rings, I have used a wire keycaps puller (got it in the o-rings kit) and that did no damage whatsoever on the keycaps. This is definitely a must-have for anyone who would want to remove their keycap for any reason!
– There are barely noticeable dents under most of the keys. It is either because they have been already removed once using their plastic keycaps puller or because it was how these keycaps were manufactured.
– Many people have complained about their software saying that it has a poor interface and is a bit hard to use. I HAVE NOT tried it since it seems like it is not available on MacOS.
Should you buy it?
If you are looking for the best most affordable mechanical keyboard, you should definitely get this! It surpassed all my expectations. For that price, you cannot not get it.
Disclaimer
I have paid this product with my own money. I would never recommend something I would not buy myself. If you think this was useful, please upvote this so more people can see it! Thanks!
1. I wanted a smaller foot print on my desk
2. I like new tech and wanted optical switches
3. The value proposition here was very intriguing.
Potential deal breakers:
1. Lighting – If you are an RGB crazed mad man, you might not want this for VERY picky reasons. The rgb used in this keyboard has two leds for each key. I have no idea why they thought this was a good idea or what they were going for but the downside to it is that you can see both leds depending on what color the board is trying to show.
2. Glossy sides of key caps if you are super picky
3. No media or volume control. (Can be remedied if you download and run auto hotkey on startup of windows. this is more of an advanced thing for someone to do, but anyone can do it, even with your keyboard you are probably using now)
Pros (in order):
1. Typing experience (Brown switch, this is my second mechanical keyboard) – For those who dont know, the brown mechanical switches have a tactile bump which is felt as a sort of wall on the key press that you break through. Brown switches are not clicky and the sound they make is muted and low tone which I absolutely love. I came from a logitech 810 that has the G Romer switch, which is Logitech’s proprietary mechanical key switch. These switches are very similar but I would say that the Gateron optical browns in this keybaord have a slightly more present tactile bump.
I was excited to try out these switches and I love them. I have been playing type racer for a couple of hours today just because of the amazing typing experience and the pleasing low bassy sound that comes from these keys. they are also a big reason why have taken the time to write out such a lengthy review for this product because i just enjoy typing on these switches so much.
Truly a pleasure.
2. Gaming (again, this is the brown switch) – I am a gamer so this point is either going to be a pro or a con in this review and obviously its in the pro list. As for the optical switches, i think the lack of input delay actually got me confused when i started playing. I read that input on other keyboards are like 30 ms while optical is bassically no input delay at all. I felt weird at first but i got used to it in a couple minutes and use the keyboard as normally would my G 810. I played first person shooter with this today and the tactile bump was a bit more of a hindrance than the G Romer switch on the 810 but i dont really mind it because i will eventually get used to it and wont notice it anymore. It is different but not different enough to were i wont get over it. If you are into linear switches than obviously you wont want anything to do with the brown switches in the first place.
3. stabilizers – the large keys like space, shift, backspace and enter all feel really solid. the space bar in particular on my G 810 along with the other keys was really lousy and am glad to be rid of it. that space bar was ridiculously clacky where the space bar on this keyboard makes a satisfying THUMP.
4. Lighting – it works. im not that picky or an rgb freak. I like a nice per key back lighting and this makes me happy. The double color you get from the weird leds is odd but its not a big deal. The instructions for how to change the lighting effects with the function + (whatever key) is all in the manual you get with the keyboard. (you can do more with the software but its not easily found and do not think most people will download it because of how you go about finding it)
Conclusion and take ways for me:
I will never buy a high name brand keyboard ever again. For what is 50 dollars, i got everything i could ever need out of a keyboard where high end brands like logitech would charge 100 to 120 or more for similar offerings. For me, spending extra money on anything else would be a 100 percent waste. I would gain nothing meaningful to me or my setup at all.
Regardless of price, these switches awesome (ive only had this and the G Romer switch by the way)
