Works just like it says.

My hands can no longer open a bottle of wine. This makes it so easy.

Keep on charging.
Color: 8-in-1 Deluxe Wine Set - Silver
Over the years electric wine openers have become smaller and more functional. Everything in this set is excellent. If you open several bottles per week, be prepared to plug in the USB C often. If this is a replacement, like it was for us, consider keeping any old foil cutters and compare them to the knew one that comes in the set.
