I bought this tiny device with hesitation due to looking at the other reviews. The device comes with security software installed on it and lots of other files. I deleted all its contents as I thought the security on it was no use to me.
I have seen others write about how slow the transfer speed is, and thought I would test this, I transferred a few folders with multiple documents in each, and it was instantaneous. Although the files were word documents/ presentations etc.
However I did try it with large media files..... such as my video folder which was around 8GB, It said estimated time was 26 mins... then changed to 30 mins... :(
So overall it's brilliant if you want it for storing word documents/ presentations/excel files etc, but not good for transferring media or rather, large amounts of media at one time :/
Hope this helps!!
