Query: Poor Quality

Was thrilled to get a 2.2 Gig portable storage device for only $80. Not so thrilled when I lost 3 days of research work!!! Transfered data to the Emprex drive while at work, verified the files after transfer and all was fine. By the time I got home & tried to upload to home PC the device heated up and would no longer function. Thought it was a driver problem but further testing revealed the Emprex was now D.O.A.I traded it in on some SD RAM for my new Palm Treo unit.This device should come with a warning lable:"The techie general has determined that use of this product is hazardous to your data ~ Use at your own RISK!!!"
