Mine was legit so I can’t complain, however, others haven’t been so lucky…
I bought one of these from Amazon as a replacement after being sent a fake one from eBay. The one that arrived from Amazon is 100% legit and has worked in my Nintendo Switch perfectly with no issues whatsoever so from me it’s 5 stars… however…Looking through other reviews, reading people’s descriptions and seeing the pics people have posted I can confirm that people are recieving the same fake cards from Amazon that I recieved through eBay. I don’t think this is on purpose by the seller as mine was legit so I think these fake ones have slipped through at some point.Some things to look out for if you do order a card and want to check the legitimacy of it:1) The packaging they sent the fake card to me in is a white cardboard sleeve with a phone on the front next to the green android robot (an example photo has been uploaded by another customer in their review for reference).Look thoroughly at the image of the phone. Is it blurry? If so then it’s fake.2) look at the card itself. Does the grey part of the card look really dark? And does the red part look like a painted layer on top of the grey part leaving a nanometre of a bump between both colours? If the answer is yes, it’s a fake.3) is the card a tight fit? Legit cards sit perfectly flush and will never have any fitting or seating problems. Those that do are usually fake.4) how much data can you fit on the card? Can you store a few gigs of data onto the card but after a certain point does it straight up refuse to transfer any more? If yes then the chances are it’s fake. Sometimes there are manufacturer faults in legit cards where they have faulty sectors straight out of the box but these are rare so it’s best to assume it’s fake. Further tests would need to be made to properly identify it.What these scammers do is they use smaller sized cards and hack the software to read that it’s a bigger size than it actually is. This was the case for my original card from eBay. The card would store 4gbs of data and then would “fail” despite saying i have over 100 gbs remaining. I first did an error test on HDtune to see whether it hard any bad sectors (it passed so it was fine there) then I did a read and write test which identified that I had in fact a 4gb card disguised as a 128gb card.Just a few things to check when purchasing cards online to help those who may not know about this stuff and to help them from possibly getting scammed. Hopefully this all helps.

Reliable but could/ should be Faster?
Reliable but could/ should be Faster?As always I buy a SanDisk Authentic card from Amazon only not any 3rd party sellers as it’s too big a risk since SD cards are probably the most Faked / Copied things on Earth ;)I bought the 200Gb MicroSd version which is supposedly a Class 10. It’s certainly not going to win any prizes on the speed stakes that’s for sure… However I had bought 1 of these cards a few months back & it was supposedly the exact same 200Gb MicroSd class 10 card & my older 1 (which was again bought from Amazon Direct no 3rd party seller) is significantly faster at writing data to & ever so slightly faster at reading date. I don’t know if SanDisk now make x2 models of the 200Gb MicroSd Class 10 U1 cards now or what but if your expecting a really quick write speed & more importantly need that fast write speed maybe look elsewhere for quicker options IMHO.The Card gets used in a device which doesn’t require a speedy write speed so I wasn’t that bothered & it’s definitely OK no problem with it & it’s 200Gb of storage space is handy for sure.So I guess overall cause of its cheap price these days that it might be the current best Bang per Buck in the 200/ 256 gb range of cards on offer at the present time.Pros: Reliable SanDisk Quality with lifetime warranty I belive + Decent read speed.Cons: Disappointing Write Speeds as a class 10 U1 card should deliver better IMHO.Recommended though due to the Pros far out weighing the 1 Con 🙂

Massive storage for no money at all.
I bought this on Prime Day for just under £10 which is astonishing given the size of it (128GB). I have it fitted to my Fire 8 tablet and it holds huge amount of films and TV series. I recently went on a 10 hour flight and watched an entire tv series which took up only 7GB. This should be able to hold a couple of hundred hours of media no problem. It is plug and play so no issues there and I went with this one due to it being a class 10 for fast read/write access and the manufacturer SanDisk have a very good reputation for high quality SD cards.

Usual sanding quality
In using this sd card in a garmin sat nav to store offline paps and music.It works absolutely fine.

Great for phone storage
This is a solid addition to a phone as an alternative storage. I use it for taking photos, videos, storing mp3s and storage for the downloaded Amazon Prime shows (really happy the App allows SD card usage).Now I wouldn’t try to run an App from it as the speed us really not comparable to the internal MMC, like almost all SD cards. I haven’t run be benchmarks but ut does seem 3-4 times slower on writes and the more the number of files the worst it scales (copying / extracting large numbers of small files is extremely slow). However this an expected trait of the format so I do not fault this item.So far it has been used for several with no reliability issues.

200GB model is great for Nintendo Switch
My 128GB MicroSD card was running low on space on the Nintendo Switch, so I needed an alternative. 256GB cards are still way too much but this SanDisk Ultra 200GB microSDXC was a great price and perfect for my needs.Moving everything over from one card to the other was simple. the card was pre-formatted to Ex-Fat which the Switch can use, and I just needed to move the folder on the root of the card from the 128GB to the 200GB on my PC.The read/write speeds have been perfect since installing the new card on the Switch, no issues with slow loading games and plenty more space to play with.Note: The SanDisk Ultra 200GB microSDXC was bought direct from Amazon themselves, you do need to be careful with third parties selling these.

Tenia que comprar dos trajetas, en un primer momento opté por ir a media mark pero el modelo que tenian no era el que estaba buscando por lo cual, pa casita que llueve, me dijeron que a unas malas la podia pedir por la web y luego pasar a recogerla…Bla, Bla, Bla… para que la voy a pedir por la web e ir a recogerla cuando la puedo pedir por la web y me la traen a casa.Y bueno llegados a este punto solo deciros que es una tarjeta micro SD bien de precio, ni cara ni barata, en la linea ScanDisk por que es una buena marca, y hasta la fecha ningun tipo de problema, procesa bien los datos en cuanto a rapidez y no se traba, hablamos que una de ellas esta puesta en un samsung galxy s7 haciendo tambien de pendrive en casa por lo que muy contenta y satisfecha
