Query: Sandisk Extreme USB 2.0 Reader

Works as advertised, super-fast copying compared to the Sandisk MobileMate reader I had for my high-speed SD cards (from ATP), and much faster than connecting my Canon digital Rebel directly to my computer. Looks good, though the rubber pad on the bottom seems to be drying out and losing its grip.
