Great!
So easy to use and the battery life is long so you’re not having to charge it all the time. We started using this about 3 months ago and the battery is still practically full. Love this set, makes uncorking wine a breeze.

Among the best!
The only automatic wine opener I found with five stars. Used it daily since purchased and agree (thus far) it has earned every one of them. I have several bottles with stubborn corks that challenge every manual opener I've had. This tool handles them with ease. Especially neat is the way it "spits out" the cork after extraction. Very attractively and well packaged. Add a little gift paper and you're set.
(Daily use since purchased and not even close to needing to be charged).
