I bought two 128gb cards and both work fine. On anything from gaming devices to tablets to cameras and so on. Transfer speeds are there in both read and write. No reliability issues at all. I've had no issues with data loss in mounting/unmounting. And they've been holding up so far.

I’m able to place multiple cards in my camera for added storage during a shoot. My camera has had issues with not writing to the card fast enough before, which can make for a very frustrating shoot. The process speed on this card is great, I normally take photos in raw, and I never have to wait to review the photos or videos on site. I’ve been using this card for about two months now, and it has yet to give me any issues when transferring my photos or videos after a job to my computer or a storage drive! Hope this helps someone!
