Pros: Supports USB and eSATA. Convenient for switching between multiple drives.

Cons: Switch won't stay on.

Overall Review: This would have been a 5 star product. The docks we purchased worked perfectly for our backups while we've had them. Then the switches started going bad. When on, they're supposed to latch in the ON position. After a period of time, though, the latching mechanism gives out. I can sometimes get it to stay on with liberal applications of duct tape, but, really! If they can improve the quality of the power switch, they'll get their stars back.
