Review on TOPESEL 5 Pack 32GB USB 3.0 Flash Drive Memory Stick Thumb Drives - Convenient 5 Mixed Colors: Black Blue Green Red Silver by Matthew Miles

, I have tried several of them. I hardly used one, two I didn't use at all, but two I had problems with on both Windows 10 and Linux (on three different machines) - on systems where my other flash drives work reliably. Sometimes one of the two doesn't answer at all. At other times they both blink once, then the internal LED stays on - and although the operating system knows something is there, it doesn't allow access to the file system. Ejecting and reinstalling the flash drive multiple times eventually allowed me to copy the files, but I won't be using them again. Unfortunately, they end up in the trash can.
