Review on 💾 KOOTION 10 Pack 4GB USB 2.0 Flash Drives - Keychain Thumb Drive Bulk Memory Stick Swivel Black by David Romo

Used to flash large (2GB) firmware files on machines. I started by fully formatting each one to make sure they all get formatted. After the initial formatting, everyone could be prevented from writing again. For the rest, everything worked at first, but when the firmware is updated, I will overwrite the disk (quick format) and overwrite the new file. The other three never worked for writing after I copied the firmware file into them for the first time. The other six seem to work fine, but I have limited faith in them. I use them for non-critical applications (if they don't work I just have to rebuild the drive on another) but I don't want to use them for anything. important. 40% rejection is terrible. I'm unfortunately outside the return period, so I just have to eat the costs. Next time I will buy discs from more expensive brands.
