Great but had a problem
It’s great except you have to finagle the darn thing for it to charge. Sometimes I have to use something to get it to lean just right so it charges. Otherwise it’s spectacular and easy to use! Love the foil cutter tbh, that works like a gem!

Nice tool, but with a 4 year life span.
I bought this on Nov. 2020, after hand surgery left me temporarily unable to do simple yet necessary tasks- like opening a wine bottle. 🤪
It's compact, nicely designed, and reliable. I kept it plugged in all the time with no issues. The only negative so far is the blue light which stays on whenever the unit is in the base, fully charged or not. (Not a fan of the many small yet bright lights from all appliances! Placing a Talking Yoda figurine in front of it blocked enough of the light to satisfy me).
I found it easy to use and appreciated the foil cutter. Worked well on all types of corks.
Flash forward to spring 2024... Despite the constant charging, the corkscrew dies at maybe a half inch into the cork. Just slows down and dies. Having read earlier reviews, I may try to crack it open and replace the battery. But ultimately, having regained my hand strength back, I'm more likely to go back to an old fashioned, reliable, hand operated corkscrew and celebrate the loss of weird lights and needed electricity.
Conclusion: unless you are recovering from hand surgery, just get a good quality non- electric corkscrew and use it for 75 years (optimistically). Best deal ever. And you can take it camping too.
