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.

Effortless and Elegant Wine Opener!
Color: 7-in-1 Black, Size: Rechargeable Set
I absolutely love my CIRCLE JOY Rechargeable Wine Opener! From the moment I opened the box, I could tell it was well-made and stylish. The sleek design looks great on my kitchen counter, and it feels sturdy in my hand.
The performance is amazing — it removes corks quickly and smoothly with just the press of a button. No more struggling with manual corkscrews or broken corks! The built-in rechargeable battery lasts a long time, and the charging base keeps everything neat and organized.
It also comes with handy accessories like the foil cutter, which works perfectly every time. I’ve used it for several dinner parties, and my guests are always impressed by how effortless it is to open a bottle.
If you enjoy wine and want to make your experience easier and more elegant, this electric wine opener is a must-have. It’s functional, beautiful, and makes a perfect gift for any wine lover! 🍷

Fabulous Product!
Color: 7-in-1 Black, Size: Rechargeable Set
This wine opener is fabulous! Foil cutter is sharp and works well. Easily removes the cork, then releases the cork from the corkscrew with a touch of a button. Also seals the wine which I have stored on its side in my wine refrigerator without any leaks. Charges quickly and I have opened many bottles of wine without needing to recharge it. Have had this item for a few months and if it continues to work this well, I will be amazed and very satisfied. Very reasonably priced as compared with similar products that I considered. Most of the other products cost more and did not do all of the functions that the Circle Joy does.
