Pen-style air pressure corkscrew requires no power to open red wine bottles.

The cutter is sharp enough but I can never cut a straight line. Thats simply me being a dumb-dumb, then. I'll drink much more to get more practice in.
The 'needle' with the air hole in it that gets inserted through the cork and into the bottle itself works absolutely beautifully. For as long as it lasts, you will have no further battles trying to get the bloo*y cork out! It's very clever and very simple. That's surely the best of design.
I was SO impressed the first time I used it.
Don't pump viciously or impatiently and it should last a few hundred bottles, surely.
Keep a good hold of the bottle in anticipation of the cork suddenly lifting out.

Fantastic corkscrew ,buy also as a gift,birthday
very good with what it says, and it also has to open the seal of the bottle, recommended

Very cool bar gadget, works perfectly. When opening, you should be careful not to pump too much pressure into the bottle too quickly. Clear recommendation from me.
