    Works OK, but BB Geek Squad suddenly required me to buy it to back up my PC during repair. I had several flash drives I could have offered & used if I had known this was necessary, but they charged me anyway without my OK!

    Works good. SanDisk seems reliable. Though sometimes there are compatibility concerns. This does seem to work okay. SanDisk is usually reliable. I like the red color as it can be hard to find these small devices.
