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.

Game Changer for Wine Lovers
Color: 8-in-1 Silver, Size: Rechargeable
Circle Joy Electric Wine Bottle Opener and I’m honestly really impressed.
Setup was super simple, and it works exactly as advertised—just place it on the bottle, press a button, and the cork comes out smoothly in seconds. No struggling, no broken corks, and no mess. It makes opening wine feel effortless and a lot more enjoyable.
I also love the sleek design—it looks modern and feels sturdy, not cheap. If you have the set with accessories, the extras like the foil cutter and pourer are a nice bonus and actually useful.
Overall, this is a great little gadget, especially if you open wine often or just want something convenient and easy to use. Definitely a solid buy or even a nice gift idea.
