Review on EATOP 512GB USB3.0 Flash Drive - Silver, Compatible with iPhone, Android, Computers - USB Storage Memory Stick Thumb Drive Photo Stick by John Floyd

I was hoping it would be ok but unfortunately it is not. First it was uploading pictures, which was easy. Then he just stopped. Now I'm trying to add a photo and what I get is a file that's 30-40 years old and when I can open it it's completely black. It also seems that the connection with my iPhone is unreliable even without a case. I may have received a defective flash drive but it is being returned.
