This is an ok flash drive for the price. It's quite lightweight and has no cap, so it doesn't seem very robust. Given the price I'm not sure it's a great deal unless you are not moving it around much and you mostly read from the drive.

Read speed for large files is 150MB/sec which is pretty good, but write speed at 7MB/sec is somewhat slow.

East to use, a good price for a good product. Would have liked a cover to pull over though. East to use, a good price for a good product. Would have liked a cover to pull over though.
