    5.0 out of 5 stars Legit card. Legit fast.
    Reviewed in the United States on March 3, 2019
    This review is specifically for the item SanDisk Extreme 128GB microSD UHS-I Card with Adapter - 160MB/s with SanDisk MobileMate USB 3.0 microSD Card Reader. My card was shipped from and sold by Amazon.com. The top review for this card would have you believe the product I received, based on physical appearance, is fake. The speed tests and H2testw program appear to indicate it achieves the advertised speeds and has the correct capacity using the bundled USB 3.0 card reader in a USB 3.0 port on my desktop Windows 10 PC.
    If this card is somehow "fake" it is quite impressive. I'm sure there are some fakes out there, but if you do decide to buy this card it might be worth performing your own tests before deeming it fake based off the looks alone (assuming it's not an incredibly obvious fake).
    April 18, 2020 (13 month update): card still works great. No complaints, I'm very happy with it.

    5.0 out of 5 stars Working fantastically for Nintendo Switch!!!
    Reviewed in the United States on January 8, 2020
    I love the product been working perfectly since the day I bought it. I bought this specifically for my Nintendo Switch. I previously had the 512GB Micro SD Card but quickly ran that up, so finally this card went on a discount and I was able to buy it!!!

    Am glad I did I finally have ALL my games on my system, no more having to delete a few here and there to make room for the next game, finally I can just sit back and Buy/Download just about anything I can get, worry free of weather or not I have enough space!!!!

    After the format I believe I was left with around 953GB and as of now am left with 75.8GB TOTAL left (Including System Memory), which is still very good at least to me since most games are 2 to 8 sometimes 12GB depending on the game.

    Anyway I have a total of 176 Games the range from huge AAA games to small Nindies (Nintendo Indies) games as well, and again am very happy with my purchase. Also you can see my current inventory of games in the pictures for better idea of what games

    3.0 out of 5 stars Fast enough to use as extra storage on Surface Pro 6 but not as fast as expected
    Reviewed in the United States on December 1, 2018
    The built-in SSD disk space is extremely expensive on the Surface Pro 6, so getting the smallest Surface Pro 6 and using a microSD card to complement the built-in storage is an attractive option in my opinion.
    The good thing is that this card performs well when inserted in the microSD card reader of the Surface Pro 6 (about 80 MB/s sequential read, 80 MB/s sequential write) although it does not reach the advertised speed (which is "up to" 160 MB/s sequential read, 90 MB/s sequential write).
    As I believe the UHS-1 standard is limited to 104 MB/s anyway I am not sure if it is possible to find microSD cards that would perform faster.
    In short a good choice for the Surface Pro 6 even if possibly not the best choice.
