A:AnswerNo need to disassemble, put the cork screw back on top of the wine bottle & push the down button. That should get cork off the screw. Good Luck!
A:AnswerI also have the $20 opener. The difference is this is taller, lighted and has the wine bottle stoppers. I didn't notice it being faster or better.
A:AnswerThe stoppers are just to use as replacement corks - they just fit snug down onto the top of your wine bottle. Unfortunately, I don't think this device removes air. But if you open a bottle one night and can't finish it all, we've found that replacing the cork with one of the stoppers is very sufficient in preserving the taste of the wine for the next night.
