So far working great!
Style: Gift Style, Style: Gift Style
Got this for my partner that needed an electronic wine opener to more easily open bottles. So far it is working great and making it much easier. I like the additional accessories and the look and feel of the opener. It looks great on our bar and a nice addition to our bar tool collection.

5 stars for the opener but the accessories........
Color: 5-in-1 Battery Operated Wine Set - Silver
Returned one of these because the wine sealer did not work. It wouldn't hold a vacuum.
Here's the thing. I'm not going to use that vacuum sealer and I don't care about "aerating" my wine with the included pourer. And I will SELDOM use the wine stopper because well ....... A bottle of wine having anything left in it after opening around here is like a blue moon on Christmas. What can I say.
But I just can't stand paying for something that doesn't work, even if I'll never use it.
Anyway, the wine opener itself is a champ. I've owned a bunch of wine openers. This opens bottles faster than any opener I've ever owned and that includes rechargeable openers 3 times what I paid for this opener.
It's worth every penny. We drink a fair amount of wine around here so this thing gets used a lot. I've never replaced the batteries. It's not even remotely slowing down. It just keeps popping out corks and it's been months.
Considering what this opener cost I don't see how you can go wrong with this purchase.
