      Great cups, already have two larger ones. Keep drinks hot and cold for ages. The large ones come with straws, would have been nice for the small one to come with a straw too.

      I absolutely love my beast. I’ve spent years having cold coffee and now my drinks are piping hot for hours! I’ve not tried cold drinks in it yet but for hot drinks it’s amazing. I use it in the house and on journeys

      Would rate 4.5 stars if I could
      Very good unit for keeping drinks hot or cold. I’d prefer if they put a rubber grip around the middle to help with holding more securely
      Overall I love using i

      Couldn’t believe how good this is at keeping my coffee hot, Made my coffee and 7am and by 11:30am coffee was at 50c even after putting some cold water in at the start so I could drink it, super easily cleaned and looks great 100% worth buying

      I have lots of these in lots of colours. I wouldn’t try any other type or brand since having these.

      Last for years. Easy to bleach stains out of. They don’t dent or scratch (not easily anyway). Keep cold or hot dependant on needs. I’ve often still had ice cubes in mine the next day still floating in the liquid if I have left some drink in there. Stays hot for hours but not necessarily all day as I leave the drinking spout on mine open to cool it so I can drink it on the go. Recommend 100%.

      The cap simply pulls off so you couldn’t leave it full in a bag as it could spill. I use mine on the go and if I need more that’s watertight completely I refill this cup from my bigger thermos flask throughout the day

      Absolutely love this cup. It looks gorgeous, it comes with 2 metal straws that have different diameters. One average size and one slightly larger for a bigger gulp. Both straws can sit in the cup at the same time if you wish. There’s also a straw cleaning brush. It keeps my drinks hot/cold for hours. I wouldn’t be without this cup.

      This cup is fantastic. It was a gift for my partner and he liked it very much. No spill, sturdy and it keeps your coffee hot for over an hour.
      Also, huge help to the environment
      Highly recommended

      Keeps a litre of tea or coffee hot for hours. 3 of these vs 7-8 visits to the kettle to fill a cup – it’s a no brainer. If only it came with a plug in spout to aid decanting into a proper cup as required. Talking of things that could be included, I’m marking it down a point because the handle is more of an essential than an optional extra and should be included.

      My usual travel coffee cup decided to fall off the side and developed a leak which wasn’t great for having coffee on the go. I needed a new one and ideally a bigger one.

      I’ve had a generic flask before and they work well but I wanted something that could also be used for cold drinks and didn’t require unscrewing a lid every time.

      The “Stanley” cups that became popular seemed perfect but the price was ridiculous and it seems they’re only used by people who need to photograph what they’re drinking on a daily basis.

      I came across this “Beast” and it is indeed a beast. 900ml of space which is more than adequate for a morning coffee or an iced drink or whatever I feel like.

      It fits into my cars cup holder and also in my cup holder in my truck which is an absolute bonus.

      I got it in the Army Green colour and it looks fab. Going to test it with hot drinks and time how long it keeps hot and the same with iced drinks and will update my review with results.

      As a bonus I also got it at half price which is a steal. Thanks Greens Steel. I’ll be purchasing more from you in the future!

      5.0 out of 5 stars It's a beast!

      Golden Review Award: 7 From Our UsersFirstly this is beautiful and very well made. Now to the title, if you want this to sit next to your desk and keep your drink warm or cold for hours it will, keeps hot drinks hot for 3-4 hours minimum.
      This is huge, the 900ml is very difficult to hold for any length of time without the handle, I have hands like snow shovels and they ache after 10 minutes of holding this.
      I bought this for work where I am busy moving lots of different vehicles around, I drive Mercedes Renault Kia Honda Ford Skoda, this does not fit in the drinks holder of any of them, the bottom may be slimmer but still very wide. Also when you put it down it’s very top heavy.
      Again beautiful and top quality but think what you want to use it for.

      This was lovely a colour and design allowing a slightly larger bottle to fit in my car cup holder slots. Comes with metal straw and fine cleaning brush, the lid just pushes onto the top of flask no locking mechanism so I would not tip it up as can leak. To access opening for straw or sipping there is a sturdy plastic cover that I find very difficult to open but I don’t have much strength in my hands fine for ordinary person. Recommended for use in upright position only, keeps drinks cold for longer periods.

      I own 3 of these now and they really encourage my kids to drink water throughout the day. Drinks stay cold and everyone has their own colour of cup so no mix ups.
      I removed the stainless steel straws from my kids cups because they are an injury risk if a kid falls whilst drinking. I use silicon straws instead.
      Today I tried my cup with the wide stainless steel straw and I didn’t like it at all! Think I’ll be switching to silicon straws too.

      First off, the colour of this tumbler looks great. I went for black which is a matte black with a smooth feel to it. I have purchased other colours since and they had more of a textured grip feel to them, I prefer the smoothness of the black but that is just my preference. I bought this tumbler for use around the house for the purpose of keeping my drink ice cold, it definitively serves its purpose and holds a decent amount of drink. I always add ice to my drink and I end up having the same ice cubes over 6 hours later. The lid has never come off on me however I don’t use this for hot drinks. I was so impressed withe the quality of Greens Steel that I purchased the 16oz reusable coffee cup for hot drinks when I’m on walks with the dog. The only thing that would make this product better in my opinion is if the bottom of the tumbler had a rubber or non slip base which would also make it quieter when picking up and putting down, it’s a small thing but I feel it would make a difference. I would definitively recommended this tumbler for the price range.

      Golden Review Award: 11 From Our UsersThis is my second time getting one (not because it broke or anything I just wanted a different colour so I gifted my old one). I absolutely love these products, it’s my first time using the handle (bought separate) and I can definitely say it’s worth the 10. I had just filled my cup with juice to the top so in theory at it’s heaviest and the handle doesn’t bend. I was worried it would bend and my hand would be pressed into the side of the cup but this is not the case. I can also slide my hand underneath the handle and hold it like that. I’m disabled and getting up to get new drinks is a challenge but with this cup it keeps my drinks cool and dog hair free all day and even overnight! I also love that I can put it in the dishwasher so I don’t have to wash by hand, something I struggle with. The cup itself is lightweight, only heavy when full and unless you can change the weight of water there’s nothing that can be done about it. There’s no metal taste or anything like that, something I struggled with other cups. Overall, this cup is absolutely perfect in every way for me and I can’t recommend enough! It even comes with a little drawstring bag to protect it from scratches or scuffs. Definitely worth the purchase.

      Golden Review Award: 4 From Our UsersI’ve only had a day so I can’t talk about durability. This cup is amazing, fits into my cup holder which a lot of other cups didn’t, despite the claims. I got the rainbow design which is really pretty.
      The star attraction is that I put ice in my cup 15 HOURS ago and it’s still there. I’d say the ice could last you 18 hours.
      The only complaint I have is that the cup already cost 25, I don’t expect you to have to pay separately 10 just for the plastic handle, it should of come with the cup and I’m not sure how durable it is going to be.

      Also once the lid is close, without the straw in. The cup becomes leakproof.

      UPDATE!!!!
      I’ve now had the cup a week and absolutely no complaints, although weirdly enough, ice is not lasting as long as it did on the first day. I’d say ice averages 8 hours before it melts which is still good.

      Also it doesn’t hold 900ml. I filled my bottle up this evening with water from a 750ml plastic bottle and it came up to 1cm from the max line.

      Lastly, I know the drinking hole is there to be able to drink without a straw which is great but once you use the tumbler with a straw, the hoke is then too big and you aren’t able to cover the hole with the lid to keep the temperature and make it leakproof. Also if you wanted to carry the tumbler in your bag for a journey and want to close the lid, there is no where to put the straw. Just a slight design flaw for my liking.

      All in all, a decent tumbler and I am overall happy with it, using it everyday.

      Golden Review Award: 38 From Our UsersOK listen up people, you don’t need to pay attention to any of the other reviews on here because I’m putting it all out there!!

      3 weeks it took me to decide to buy this 40oz Beast and I am so glad I did! Let me break it down for you!

      So firstly you have all these “the lid doesn’t stay on, this is rubbish” or “it doesn’t push down so is unusable” reviews. Well the truth is if you actually take 30 seconds to read the little bit of paper that you have to pull out of the Beast then you will know exactly how to stop that happening! It is simple…

      Hot – pour your drink, let sit for 2 or 3 minutes, place lid on, and it goes on wonderfully!
      Cold – fill and put lid on.
      Troubleshooting – should you struggle to push the line down, or you find it pushing up once on, open the drinking hole and push the lid down, then close the flap! Simple!

      OK, so it isn’t leakproof but it really is great. My cup got knocked over by a couple of kids kicking a ball (not their fault, I was sat on the floor and it was just a bad shot!). The cup was open, with a straw in and I lost less than a mouthful!

      Now I’m not the biggest of people and because the Beast really is massive I was a bit worried that my little hands weren’t going to handle the sheer girth, especially with the lack of handle. However, I’m please to announce that I can handle it just fine since the bottom isn’t much wider than a mug!

      Now the all important temperature thing! So I set off on a 6.5 hour drive. I made a coffee (equivalent of 3 cups) about an hour before I left, just over 4 hours later when I finished it the coffee was still hot. Not warm, but actually hot! Cold is even better! I poured a whole carton of caramel iced coffee (don’t judge, I was on holiday, just me and 2 kids so I needed the caffeine lol) I finally managed to finish it 6 hours after it was poured and it was still ice cold, without the addition of any actual ice!

      Now if you’ve made it this far, I think that’s enough reading for the year, now go and buy the 40oz Beast because you really do need it!

      5.0 out of 5 stars WARNING reading this might make you buy one!

      This is a day 1 Review so as to durability I dont know but the feel of the Cup is it will be fine. I love this cup and has a couple minor drawbacks but its nothing that cannot be solved.
      Positives are.
      1. 2 hours after filling this 40oz Beast with an entire pot of coffee it was still pretty much as hot as it went in still a little too hot to drink so would suggest maybe making it only slightly hotter than drinking temperature. I take it Black so no cooling down with Milk for me.
      2. It looks Great
      3. Spares generally easy to get a hold of as advertised
      4. Solid Construction
      5. Finish is great.
      Negative points for me are
      1. That doesn’t quite fit in my Pickups cup holder to the bottom but I can fix this.
      2. It is huge. I have large hands and at top i can only get half way round making it akward to hold from here. But I can fix this by either holding at the bottom and get used to holding the cup this way or purchasing the Handle from the website when it comes back in.

      Overall I love this cup and the Yellow I went for Pops so No matter where I put it down I will find it. Finally I have a cup that suits my caffeine needs. you wont be disappointed if you purchase this cup.
      Buy it.. don’t hesitate its worth it.

      Golden Review Award: 6 From Our UsersThis arrived just before the hot weather made itself known here in the UK.

      I had intended to use it for coffee, but given the weather I’ve been drinking water instead. This kept the water cold to cool for over eighteen hours – that was with quite a lot of ice added to the water – which impressed me greatly. The straws and straw cleaner were a nice added touch if you wish to use them instead of sipping the drink through the lid opening.

      The lid fits well. Because it’s a push down lid, opening the sip section will allow it to seal better because it releases the internal air pressure. Once that pressure has equalised, it fits snugly. A push down lid is not going to be 100% water tight, but it should withstand small possible spills, so long as it’s not laid out on its side or upside down. I will always be transporting it in an upright position to reduce the spillage risk. This doesn’t mean it’s going to leak at the slightest hint of a tilt to the mug, but obviously common sense dictates that screwed on lids tend to have a tighter seal than push down lids.

      If it keeps my coffee anywhere close to hot for a couple of hours I will be more that happy.

      It was very easy to clean, as was the lid.

      Overall the build quality looks good, and I hope it lasts a long time.

      For the size and build quality, I think it’s reasonable value for money.

      Golden Review Award: 41 From Our UsersIt is so rare to actually purchase something nowadays and genuinely get what you pay for! Or to put it in a better way, something of decent quality.

      As many cut corners or try to find ways to min-max profit, quality is rare (unless you pay exceptionally high prices for something), which not many of us can do and when you do get excellent quality for a reasonable price it’s a lovely and rare feeling 🙂

      Pros:
      *Huge capacity 40oz (1136ml) Over a Litre
      *18/8 Food Grade Stainless Steel
      *Insulated Vacuum Layer
      *Hardwaring Slightly Textured Coating helps me grip. Great colours.
      *Decent quality Thick, Food and Heat Safe Plastic Lid, With clever leak proof seal and nice simple hinge.
      *Easy to clean, keeps an entire pot of coffee hot for at least 6 hours, keeps cold drinks cold (Ribena and Ice still had Ice in it all day).
      *Comes with Two Stainless Steel Straws and a Straw Cleaner. Nicely Packaged with a lifetime guarantee.
      *Simple, straightforward design, it works unlike other brands with smaller cups that I’ve tried which leak or break almost immediately.

      Cons:
      *Handle (Also cleverly designed and good quality moulding and material) sold separately but I can forgive this because of the exceptional quality and need to recoup material costs for production.

      To sum this up it inspired me to give it this glowing review which I rarely do, It’s easy to maybe look at the price and think it seems a bit high but for less than thirty quid it really isn’t, this simple design with quality materials IS NOT cheap to produce, they are making a profit but the price is fair and equivalent to a top end big brand, with I think better Quality and beats a cheap plasticy generic version with poorer materials hands down. Dont spend a fiver and dont spend fifty quid get this instead.

      Time will tell how well it lasts before the lid looses pressure or leaks or if it scratches, but I can tell for the quality it is, that even under my heavy use it should last for a fair and reasonable time, they do have a guarantee and I’ll happily give Greens Steel more money for the next one even if its not under warranty. Buy One it’s phenomenal! 🙂

      Golden Review Award: 4 From Our UsersI LOVE this tumbler! The colour is gorgeous, the quality is great and the size is perfect. I can’t comment on its ability to keep drinks warm however its ability to keep drinks cool is good. It is easy to clean and comes with 2 straws (one thick and one slimmer). I wish the handle was included in the price as it seems ridiculous it is almost as expensive as the tumbler itself! I also wish the metal straws had rubber tips as I hate the feel of metal so close to my teeth, so that was another added expense – to purchase rubber tips. However all in all I am very pleased with my purchase and have used it daily since purchase. The size of this tumbler is 1ltr which is great as I have to fill it up less often. However, despite the impression it would fit in my car cup holder it doesn’t! Thus isn’t a big issue for me though.

      5.0 out of 5 stars Brilliant!
