Easy to use, it allows to open the bottles without the cap breaks. And better, thanks to two levers, even the usually difficult caps withdraw very easily. The advantage here, no effort to open a bottle difficult. The bottom of the levers is covered with rubber or equivalent material suddenly, the hands do not slip. It's nice.
The handle doubles as a bottle opener for bottles of all kinds (soft drinks, beers etc).
Ultimately, a good corkscrew to a lower price.
