    Decent build. I have two, one that I've had for a few years. Still working well. Hasn't broken or had any structural breakdowns. Does get warm at the metal during high speed transfers, but doesn't seem to affect the speed or device. Just watch your fingers.

    Fast and efficient, the only down side is it's a bit wide, so depending on how close together your USB ports are, it might be a bit snug.

    I have used flash drives to backup operating system and for photos and documents. I prefer the larger flash drives so that I only need to use them a few times a year.
