I want to share my experience with San Disk Pen Drive. I use it for Data transfer in office. I have been using this Pen Drive since Last 8 Year. It is very useful and portable Pen Drive. The other Pen Drive gets corrupted, but it does not. I can say from my personal experience that this Pen Drive is very useful and user friendly. I feel very comfort with This Pen Drive. Its Installation is not difficult. If there is any malfunction, it becomes easily replace. Company provides good Service as far as I know. But it is necessary to save from water. If we use carefully so no problem will come. Its frame is made of plastic, which does not cause of current. I think this is good.
