Do not waste your money on this product
Background: i am an enterprise deployment project engineer for a major computer products/services provider. I have built every desktop computer i have ever owned, from the motherboard up.Pros: compact, easily transportable.Cons: does not maintain connection. Uselesstroubleshooting steps taken:high-pressure air blast to remove possible particulate matter. Used 4 different usb 3.0 connection cables. Connected device to five different hdd's on four different computers (one linux mint 14, one windows 7, and two windows 8). Connection always lost after one to two minutes. All five hdd's were 2.5" laptop drives, and known good, with other connectors. This product is cheap for a reason: it doesn't work. It is quite possible that i simply got a bad unit. I'm not willing to risk buying another, however, since i have ordered several different types, and this is the only one that has ever failed so miserably.
