Review on 📷 ProGrade Digital V60 microSD Memory Card for DSLR and Action Cameras - High Speed File Transfer & Large Storage - 64GB Capacity - Up to 250MB/s Read & 130MB/s Write Speeds by Paul Abs

I bought this card 2 months ago and it has worked great - very fast. Then last week I removed it from my camera and none of my computers can read it (including mount) and the camera I just removed it from can't see it anymore. It's completely dead. Claiming it was still under warranty, I emailed ProGrade Digital three times and called twice and left messages on the answering machine with no response. I'm beginning to wonder if this company has gone out of business. So be careful this isn't a cheap card and if it dies on you you won't be left with anything.
