I got tired of seeing my sister-in-law using the hand held manual cork screw. It was painful. Even more so when I insisted on opening the wine for her. So I decided to get her this as a gift and she loves it! I haven't used it yet because she won't let anyone touch it so I can't speak for it's functionality. But judging by her reaction, it's incredible.

Pros: Good Price, Lightweight, Easy to use
Cons: Just a little loud when operating
