Review on High Speed Class 10 256GB Micro SD Card with Adapter for Nintendo Switch, Phone, Tablet, and PCs by Jeremy Carpenter

Do not buy this card. This is the worst and most unreliable storage device I have ever had. The first one I received worked in my phone for a week. Then it became unavailable for my phone. I managed to recover most of what I moved there, but a significant part was lost forever - damaged. I worked with Revain Tech Support over the phone for an hour to troubleshoot the issue and was unable to do anything. They sent a replacement and it went right out of the box. Do not buy!
