Query: Fast & easy

I received this as a gift last Christmas. I have used it consistently now and it never fails. It is almost too easy. The trick is to hold the bottle so that it does not move, preferably supported by the counter, and lightly press down with the opener. Once you get the trick it is like slicing a piece of cake. No messed up cork screws just a smooth opener. It takes up very little room on the counter and once charged works for quite a few openings.
