I ordered 1 and was abit skeptical at first given the amount of fake cards on the market from unknown sellers. This is critical especially if you are using the Nintendo switch with ExFAT format or want to store/transfer large files. I have tested this card in FAT32 and ExFAT formats. I am very happy to say that this card is real and have yet to face any issues or corruption of data. Therefore I have purchased a total of three 256gb cards from this seller and am happy to buy more (perhaps larger than 256gb on my later purchases when I see a bargain/discount/sale)
These are genuine Samsung micro SD cards and are nice and reliable and fast. The only difference between these and the standard Samsung micro SD is that these are designed for Amazon. You get the same speed and reliability at a much lower price. Haven't seen them as cheap as I have found them on Amazon.
I got this to replace an old card in my phone. There has been a noticable improvement in speed but more importantly my batter life has significantly improved compared to when using the old card. Definitely happy with this card
Got this to increase the hdd capacity of my M/S surface formatted to NTFS and transferred my data and it now works fine would recommend this over some of the more expensive sub cards as it works flawlessly
I am very pleased with this memory card which was installed in my android phone. It is fast and works perfectly well. Up to now I have notice nothing to complain about. As usual delivery with Amazon was not a problem.
