5 out of 5 eggsWhat I was looking for

Pros: Small compact unit, Plug & play. It doesn't get any easier. It can be taken anywhere you might need to use it. Your not stuck with it installed in your system.

Cons: The cable should be longer. I' going to look on their site to see if a longer one is available.
