Pros: Small and easy to set up.

Cons: This item's description is very misleading. It does not support surround sound through the S/PDIF port. Optical connections, both input and output, are both 2-channel (aka, stereo). Nowhere on the product page on newegg, the company's product page, or the product packaging or documentation does it state this. Annoyingly bright LEDs. Constant, low volume sound (white noise) from S/PDIF.

Pros: Cheap, slim, light weight, easy to install HDD.

Cons: eSATA did not work. It's not user error. Other devices work with the same cable.
