I have two PCs. I have 4 new Sony A7RIIIs and 2 very expensive Sony Tough 64GB G V90 UII cards for my professional photography business. I have a PC with TR4 Thread Ripper AMD USB 3.0 3.1 Gigabyte x399 1920X Win 10 Pro system with more hardware than I want to discuss here. I bought this card reader and cards together to take advantage of local transfer speeds when I couldn't connect my system. One of the hard drives slowed down the write speed to the interface speed - and the Sony card reader stopped working on my PC. It cost me more to send it abroad and have it repaired/replaced than I paid for it and I got a return window on Revain.com. I'm very disappointed and that's not enough. I can't believe there isn't an official workshop in Illinois. I assume he went back to Sandisk.
