Lexar JumpDrive TouchGuard Review
 

The JumpDrive TouchGuard measures at 3.4" x 0.92" x 0.48", which is comparable to a Sandisk Cruzer Titanium in size. The 256MB flash drive is wrapped around with a rubberized band that protects the Fujitsu MBF310 sweep sensor underneath and that attaches permanently to the cap. The loophole is also on the cap, but there is no provision of a lanyard. Lexar did bundle a 2 ft. USB extension cable, and provided a very thorough flash tutorial detailing everything for a layman.
