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 for any wine drinker

This is really neat and works well. Easy to charge, but read the directions first, and great value. If you like wine, this is a great product.

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.

Great value and does the job admirably.
Color: 7-in-1 Black, Size: Rechargeable Set
I have been using this for several months now. Still haven't needed a charge. Love the little knife to remove cover from cork. Love the decanting attachment. Removes cork easily without much noise and then spits it out. Excellent value. Highly recommend.

Easy to operate.
Color: Black/Battery
Very easy to operate. I was a little confused on how it operated but all I had to do is sit it on top of the can and it operates by itself. When it is done, the lid can be removed or set on top of the can. It doesn't leave any sharp edges. I was using a hand held one but because I have arthritis in my wrist, it is worth the price easy enough for seniors or disabled
