Review on 512GB Micro SD Card (Class 10 High Speed) SD Memory Card/TF Memory Card With SD Card Adapter For Camera by Justin Pavelko

I'm not entirely sure why I decided to try this over sticking with SanDisk cards but live and learn. I have one of these and one of the Alisinsen cards, both 128 gigabytes, and have had the same experience with both. I put them (one by one) in my tablet to use as internal storage and started the formatting process. My tablet requirements are up to 128GB for expandable internal storage and Class 10 or higher. At 20% he froze. I let it sit for a while thinking maybe I just unluckily got a slow card. When I checked a few hours later, the tablet said there was no disc inserted. Impossible because I knew I had just inserted it. When I clicked the icon specific to the drive slot, it said the card was corrupt. The same with the other card. Now both are in an envelope with Revane's address. return to it. :(
