The Vacu Vin Winged is easy to attach to the bottle. You place this corkscrew on the bottle and then you can turn the corkscrew into the cork. When the arms of the corkscrew are up, you can squeeze the arms. This loosens the cork and you can vertically remove the cork from the bottle. By removing a cork vertically, there is less chance of the cork tearing or crumbling. The corkscrew fits almost every bottle, making the corkscrew almost always useful.
