Nice features
I have only had this item a few weeks. But I like it very much. It’s better than the one it replaced. I like that I only have to press and release the button to pull out the cork and then it releases the cork automatically. Only charged once so far and is still fully charged. Also a blue LED is lit when cork is being removed and a red LED is lit when it is releasing the cork.

Don't Waste Your Money!
I thought this was going to be good. First bottle opened OK, though the device obviously struggled to get the cork out. Used for 3 or 4 bottles. on the last two, I had to manually turn the device to get the corkscrew in - then pull the cork out. Cork is in the device and it won't come out. UNFORTUNATELY I THREW OUT THE PACKAGING, SO NOT SURE WHAT IF ANYTHING I CAN DO WITH IT OTHER THAN THROW IT OUT. NOTE: I did try recharging the device after each use, though it made no difference.

Works great! Better than a Rabbit brand
This is an awesome opener. My husband originally got me one for Christmas for our lake place. Everyone that uses it loves it. I had a r
Rabbit brand at home and it finally wore out, but never worked as awesome as this one. My old one also required it to sit in a plastic base as a means of charging versus a cord I can simply plug in and hide. I like this style better because I can put it on a cute little tray. To work it, you simply push a button and it pull the cork out and then releases it without having to hit a different button. This one was on sale too, so extra bonus.

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.
