I love this little beauty! Works like a charm, and is slightly smaller than its competitors, so it’s easier for packing and portability. I’m a flight attendant, so I actually use this on the plane to open bottles in premium class. It’s sharp looking too…and the attached foil cutter is well designed.

The best electric opener by far!

Color: Stainless Steel, Size: 4-in-1

This is the 3rd or 4th opener I've purchased in the last two years. This is by far the best! Top reasons this is the best: #1: it has opened every single bottle I've tried - even ones the other struggled with #2: press the button and let go; you don't have to hold the stupid button in (great for folks with bad thumbs) #3: I like the light #4: Battery level indicator and battery life ALL THIS translates to great value, ease of use, great cork removal The only thing I didn't like is that there is no stand per se (it rests on the foil cutter). Easily solved with several stands from the other inferior openers
