Champagne Stoppers by Kloveo - Patented Seal (No Pressure Pump Needed) Made in Italy - Professional Grade WAF Champagne Bottle Stopper - Prosecco, Cava, and Sparkling Wine Stopper - Chrome, 2-Pack

Very simple - no pumping required - but, they really work. The longest I’ve managed to keep an opened bottle is only about 4 days but it was as fresh and fizzy as it was when first opened. I particularly appreciate how securely they fit on the bottle - no more popping off unexpectedly and frightening the life out of you. However, they are still quite easy to remove. I have tried quite a few of these types of stoppers/savers and these are, by far, the best ones I’ve ever used.

Lovely product which oozes class! Items are as beautifully designed as they are functional. Additional touch of class is that Kloveo send you a thank you email after the purchase with additional instructions on how to use. I've now used and it works exactly as described. Fizz kept in the bottle. I even turned my bottle upside down after putting on stopper and not a drop of my precious prosecco came out! Absolutely wonderful!

They’re the best stoppers I’ve had! Sturdy and keep all the bubbles in! Thanks

A very simple and effective idea. The stopper is easy to apply and it stays on. A regular stopped can be pushed off the bottle by accumulating bubbles - whilst this one stays and keeps all the bubbles in. Brilliant!

I have been looking for a high quality champagne bottle stopper for some time. I bought the twin pack as it represented better value than a single stopper. My only criticism is that the metal edges on one of the stoppers are quite sharp, perhaps a defect. However, the product works well keeping the fizz in champagne for a couple of days after opening.

You may not often have any left over champagne (or prosecco or cava or any sparkling wine) but even between glasses it's worth recorking the bottle to keep the fizz going. I saw these in a Champagne house in France and they're worth it. Also make a nice gift!

It does exactly what it is suppose to do. Keeps fizz in and easy to use. Very pleased with purchase.

We bought these stoppers after reading the reveiws. All I can say is that they work! We opened a bottle of Prosecco the day before we went on holiday and 3 weeks, yes 3 weeks later the Prosecco was still sparkling! I admit not like you just opened the bottle but it still went pop when we removed the stopper, so impressed. They claim it can keep Prosecco fresh for a few days, more like a few weeks! If youre throwing flat Processo away, get these they'll pay for themselves in a very short time.

Years ago, was gifted a couple of these, by the marketing rep for the Conegliano Valdobiadene prosecco region. They weren't available for purchase in the United States at the time. These have never leaked, never opened inadvertently, have held up to years of professional bar use, on catering events. These Kloveo's are the same as the ones I was gifted years ago. The pictures show the new Kloveo on the left, next to one of my originals, which has been in professional service for almost ten years. Bought the two pack, and the lock cage on one is not set quite straight. Seems to work fine, just not as smooth in use as it could be. Minor thing, I guess. Seals fine. I saw the reviews nothing QC issues. There's going to be manufacturing defects sometimes, with anything. It's frustrating, but these really are the most solid performing sparkling wine cap design I know of, and I've used most of them. My original set have been banged around a lot, and work as well as the day I got them. Occasionally, wine gets through the little vent hole in the silicone seal, and becomes oxidized. It's a pain to address, because there's no good way to rinse it out. My solution is hydrogen peroxide, wooden toothpick, and a pair of rubber or nitrile gloves. Chlorine bleach works too, but can oxidize the rivets on the swivel, and maybe weaken the hard plastic parts. It could also affect the flavor of the wine. Hydrogen peroxide breaks down into oxygen and water, has never caused a problem for me. I've had success with the drugstore hydrogen peroxide. Some non-chlorine bleach is just hydrogen peroxide, water, and citric acid, would also work well. It's basically twice the strength of the drugstore stuff. It's tedious to get the hydrogen peroxide into the silicone nipple, but it does bleach the issue, and you don't have to try to rinse it back out. It won't adversely affect the wine. These sparkling wine stoppers are well worth having. Best you can get, imo.

I don't like to write bad reviews, and I always wait until I have tried something for a while before reviewing it. Save your money. If you can find a sturdier one in a wine shop, go for that. This comes apart and is a huge disappointment. I was going to gift them to people at Christmas, but I tested one first. I would never give one of these to someone I liked.

Did the job but break in less than 2 months.

These are very nice stoppers and since we use them for Prosecco it's only fitting they are Italian made. Seriously they hold pressure for at least a week and are easy to put on and take off. Still get that "Pop" when opening.

Best stoppers ever!
