Pros: Useful combo cable

Cons: None if the data cable is an appropriate length for your situation.

Overall Review: The specs/description are misleading. The Molex power adapter portion of the cable is 6", the data cable is 18" (1/2 meter). I didn't quite catch this from the photos of the item.

Pros: Solid Construction. Good desk clamp, can be turned around and bolted to side of desk, etc., if there is insufficent ledge to grasp.

Cons: Upper clamp cannot be completely tightened down on post (by design). It is intended to be able to rotate, but this merely allows it to slowly work its way down the post until stopped by the cable guide (pinching your cables in the process). If you leave the cables out of the guide, then you're ok, but you're still unable to specifically set the height to a different position without rigging up some other type of clamp underneath the arm.
