This is a very versatile memory stick, very useful for backing up files on your smartphone or copying/transferring them elsewhere. The slide is easy to use and keeps the USB plugs clean as they can be retracted when the stick is not in use. I've used mine with various Samsung and HTC smartphones without any problem.

Excellent quick delivery. Dual Memory stick works fine although does not have any loop to fasten to a key chain etc.

Very fast write and read speed. Lost 1 star due to it gets hot
