Review on USB Jing Portable Rotated Computer by Joseph Swanson

I uploaded a 4GB video to this drive and the copy speed was very low, around 106Mbps, so for 4GB it was a long time then I tried to play the video of the ride. and this file didn't play on any of the video players I had. For troubleshooting, I downloaded this copied video file from this flash drive to the computer hard drive to see if the speed of this USB flash drive is the problem, but this file I previously copied from the flash drive to the local copied the computer's drive I'm still not playing. Any file I try to copy to this flash drive gets corrupted. I am returning this item disappointed. Am I alone with this problem? Or do others just not take the time to write honest reviews?
