I had had it with cheaply functioning wine bottle openers!
Color: Silver, Number of Items: 1
I like a manually functioning wine bottle opener. This one is smooth and easy to use and I didn't feel like I would cut my finger when removing the cork from the opener. Would definitely recommend!

Not total garbage, but not high quality either. Looks, feels, and performs like a cheap wine opener.

Quality wine opener.
Color: 7-in-1 Silver, Size: Rechargeable Set
I really like this wine opener. It's well made. The foil cutter is metal unlike the last one I had that was plastic and broke. The wine stopper works well to take air out of the bottle and seal it. It also has a cool blue light that comes on when in use and charging.
