Q: This corkscrew is poorly made, consisting of low-grade stampings and flimsy plastic molded parts assembled with tinned rivets. It feels like it's going to come apart in your hand, and it requires considerable care to use it safely and effectively. It's outrageously overpriced, too. An unfortunate product offering from the company that brought us the legendary original Screwpull, perhaps the handiest corkscrew ever.I did manage to pull a cork with it, though - which is why it gets even two stars.

A: Negative

Q: I bought this to stay in my daughters dorm room where space is limited and it worked great. Don't need a pump its all built in. Stayed 5 nights and added air with the flick of a switch, I like it very firm. Would buy another if needed.

Positive
