The hinged bootlever works well and doesn't slip off. It is incredibly smooth to operate, both on the *-in and levering-out portions of opening a bottle. Twist it in and slide it out in flawlessly.

The hinged pieces that sit on the lip of the bottle don't flex, so they're unusable. This is purely moronic engineering because they made the hinge literally work against you.

The de-foiling blade is not particularly sharp either. The knife is serrated and doesn't cut the foils. The foil cutter is very difficult to open.

The needle is so thick that destroys the cork and it only has 1 hinge level. The cork screw itself is too thick, and is chromed for whatever reason. When you open the c cork screw it is supposed to stay in a certain position so you can inset it.
