Purchased after upgrading an Galaxy S5 to an S8. The existing 128 gb card I had in the S5 would not read in the S8 after a few days, but would read fine in computer. I copied the old card contents to computer then out to this new card. Opened right up in S8 and has been working great since.

I bought this exact same one from Walmart. It makes my Raspberry Pi a much usable desktop computer. Previously I was using a U1 Samsung 32GB micro SD card, when I downloaded something from the internet, I could see the bottle neck was on the disk IO. The write speed was at most 5MBps with the old U1 card. With this new U3 card, the bottle neck is at the internet download speed. The disk write speed is stablized at about 10MBps with this card.

Used this for additional storage in my Samsung Galaxy S8 and it works great. Lots of room to store my pile of digital junk now. :-PThe adapter is solid and I use it for adapting another microSD card in my Nikon DSLR which only takes SD...

So far, it's working well in my Blackvue dash cam. We'll see if there are any reliability issues in the long term.

No issues at all in a Samsung Galaxy 9" tablet, was recognized instantly. I could move and applications and data right away with no discernable difference in performance or reliability
