Wonderful opener
Color: Black
FINALLY!! A product that works efficiently, exactly as promised, and does an excellent job with no learning curve. This wine opener is easy to use, and works exactly as it should. The capsule cutter works like a breeze, and the cork lifter is smooth and fast. It pulls the cork, then reverses, and pushes the cork back off and into your waiting palm. Totally impressive! Wish all products were made as well.

Great wine ipener
Color: Black
Works great and good cutter. I wish the base was a little smaller I don’t need to display the wine aerator so it would have been better to make the base small and just be a charger and bottle cutter holder

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!
