Nice Micro SD card for phones and tablets. While not the biggest storage size, its a decent enough size for most people likely to be needing a storage card on their electrical devices.
The type, class and rating are good for every day use, and ive had a few of these cards and all have been excellent. Have now bought another for my dashcam to every day use.
I bought this one for my Walkman which had to be setup by the latest installed software, in the device which formats the card.
Just like the mobile phone uses an additional memory card with a larger capacity, than the built in one in the phone.
The same way far the Sony Walkman I have, I should have bought the 512gb rather that the 256gb one , as they fill up quicker.
My advice is to see how much storage space you have used, and the double it!
The manufacturer of these memory cards is one of the best I have used, as I have bought memory cards for my Nikon D850 DSLR camera.
You can’t go wrong with this manufacturer as the high quality of the integrity over the years, is very good!
Bought for an up coming ski trip. Is compatible with the go pro hero 8 and provided nearly 5 hours worth of memory space shooting in 4K. Will see how it holds up in the cold and adjust the review if needs be.
Brought for the switch thinking it would be more than enough for games.
What I hadn’t realised ( as I am still coming from the old school physical game era) is that almost all games nowadays is not really owned by you and can be pulled/subscription based at anytime , also your not getting the full game in many instances and have to purchase add ons if you want more of the game. So my Gigantic 256gb memory card is now down to about 32gb due to the business model of not having a physical card( granted it is convenient) but had I realised that there was so many games that would not have the card I would have looked at something like a 1tb memory card.
The usual high standards from SanDisc which arrived promptly and on time. Whilst I have not as yet used this latest purchase, I have another of these in my phone which works flawlessly and is fast. So, expect this one to be similar.
Generally, then, buy with confidence!
After hearing stories about fake cards being sold as genuine cards, I messaged Scandisk as soon as I received it and after them asking for some pictures of the card and answering a bunch of questions they confirmed it was genuine.
It was a great price and works well in my Insta360x3
Would definitely recommend
Fantastic micro SD card it’s a genuine product to which is always a relief, good price for something that will last a very long time, it’s always worth spending a bit extra when it’s your data.
Bought for “Derek Cam” so we can keep an eye on the father in law from afar. Holds plenty of footage and get over written constantly. Hasn’t skipped a beat and all footage is there if needed quickly from afar.
Arrived quickly, and good price – amazing how these get cheaper and cheaper. Already have two for my Go Pro and picked this one up to give me a little more storage options when away on holiday.
Great quality, fasts and handles high quality video from a Gro Pro Hero 10 with no issues. Comes with handy adapter although my card reader accepts micro SD so will be stuck in a drawer somewhere.
Have been using SanDisk products for years and have never had any issues. Bought two of these large capacity micro storage cards for our phones as we store lots of photos on them of family weddings, children and grandchildren etc. Very quick transfer over from our old cards and tons of spare capacity left to add more, job done. Not much else to say really, they work a treat.
We wanted something cheap, good quality and easy to accommodate the additional space needed for Legacy, Zelda and Various other games on the Family Switch. High Speed and good delivery times, with a cheap cost too – Extra 5% voucher really nice too!
Purchased this SD card for my Nintendo Switch Oled and it performs like a dream. All the games run smoothly and I haven’t run into any problems. If you have a Switch I would recommend getting it. You won’t be disappointed.
On the other hand, Amazon gave me a bit of anxiety with the delivery process. Says it was delivered through my letterbox and it wasn’t. Looked around my safespace areas, asked my neighbours if they received a package from amazon, and nothing.
So I went on to customer service chat and they told me to wait until Saturday for the SD card to be delivered as it might turn up. Thank God the delivery was actually made later on in the evening by Amazon. They gave me a bit of a scare but other than that I’m happy.
I’ve never experienced an issue like this with Amazon before but they should definitely look into keeping their delivery status more accurate as it can cause unnecessary stress and anxiety for the customer.
I needed a large capacity SD card for my dashcam to record a long road trip. The 128Gb SanDisk was big enough and has given good quality recordings and has worked reliably.
I used this for the 3DS and it works exceptionally. It is very fast, runs all games perfectly and there is never any issue. I have also used a SanDisk SD card in my Nintendo switch previously for many years and it works perfectly. The best choice!
Read only mode so unable to write to it on my laptop so had to buy a usb card reader to write to it, unsure if it’s laptop driver, hardware or so card issue but Google has many people complaining of san disks being write protected.. and no it wasn’t locked!
I actually needed for a recent purchase and everything went together even though I am not liking Micro cards for many reasons personally. I have not got a card reader so am going to have to get a USB one.
I personally like to use Sandisk as it is reliable and seems to be the ‘go for’ SD card for cameras etc. Never let me down yet.
Perfect delivery as usual from Amazo
Well packaged, fair price, same day delivery, comes with SD card adapter. Use these for my eufy indoor cams, no quibble from the camera, takes seconds to format for use. I use them for continuous recording which is aproximately 12 days worth of footage, so should last about 16 years before it needs replacing! All in all, a good MicroSD card for a good price.
The SanDisk 256GB Extreme microSDXC card, accompanied by an SD adapter and RescuePRO Deluxe, has proven to be an excellent choice for my dash cam. Its impressive speed of up to 190MB/s ensures fast recording without encountering any issues. This product offers exceptional value for money, boasting a substantial capacity that allows for extended usage without concerns about storage space. Overall, I am highly satisfied with this purchase as it perfectly caters to my needs
Needed to replace a previosu card that had failed.
This is very good indeed, the fast transfer rate is clear to see (compared to the old card) and cannot be faulted.
I bought this micro SD card for my Nextbase dash cam as it needs a fast micro SD for 4k. It is a lot cheaper than Nextbase’s own cards so definitely worth the saving. The card is fast and reliable and I have had no issues with it so far. I would definitely recommend this card to anyone looking for a good quality micro SD card.
