Small yet mighty
I love this wine opener. Its small footprint on my countertop is just perfect. It has a little light when it’s charging and I love the accessories. It’s very nice for its price. I got it before the holidays so I can honestly say it got a lot of use and it’s working like a champ!

Brilliant design and features.
Color: Black
Far better than yesteryears models. Very powerful with a lot of cork torque! The long USB cord is a HUGE plus to reach distant outlets. Charging base is another big plus. Don't forget to see the video of the girl who is promoting it but cannot figure out how to use it!! Hilarious.
