Very easy to use to open the wine

Instructions were not clear enough, instructions about the bottle stoppers. The opener aprons well though. That was very easy once charged.

Vendor support is excellent
Color: 7-in-1 Black, Size: Rechargeable Set
UPDATE 2: The vendor proactively reached out to me and sent me a replacement. The replacement works well so I’ve given them 5 Stars.
UPDATE: It really doesn’t ever go in straight so every cork is at risk for breaking off. I lowered rating to two. It ultimately works about 85% of the time.
Meh. Works most of the time, but has issues. It wrecks corks much more often than the Brookstone one we had before. It seems to twist in sideways so that it runs along the glass of the bottle neck instead of straight down. This causes it to destroy the corks fairly frequently… and on occasion it destroys it so much that you can’t get the cork out at all.
Pros:
Quiet
Has the bottle sealers and suction.
Recharges on base.
Cons:
Damages corks
Sometimes destroys corks to point of not being able to extract them.
Goes in crooked.

Great value and works well
Color: 7-in-1 Black, Size: Rechargeable Set
I wasn’t sure this would compare to the name brand one I’ve had for years but it finally died and I needed a replacement. The Circle Joy amazed me with how easily it removes corks, ejects the cork and vacuum seals the bottle when you’re done. Some reviews mentioned they were concerned with durability but it’s still working great and no signs of wear after two months of regular use.
