Pros: Pros: Almost everything about this design is quite good - the drawer goes in snuggly, makes a good connection, power & activity lamps on the front are nice. Everything is great right up until...

Cons: Cons: after removing and inserting the drive drawers a few times, the weak link is quickly exposed: it's the little key-lock/latch mechanism. As soon as the latch meets any resistance at all - which it often does even when the drive has been carefully and fully inserted - the (plastic, of course) locking mechanism breaks apart from the latching lever. Then the entire unit is toast (and you may or may not get a drive drawer stuck inside). This is NOT particular to one faulty unit - I bought six of these, and one by one they all failed in the same way. STAY AWAY!

Overall Review: If anyone discovers a well-made mobile SATA rack drawer/receiver combination, would love to know about it. Would glad have paid twice as much $ for trouble-free well-designed hardware. But these are cheap...and you get what you pay for.
