Champagne Stoppers - WAF Patented Seal - Made in Italy - Gold

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.

Works good at sealing the prosecco and saving it for another couple of days. Maybe more. Haven’t finished the bottle yet. Haven’t checked to see if it is leakproof because the bottle is upright on the frig door. It’s a good product. Update: it’s been a week and still bubbly.

This champagne stopper is wonderful. I can open the bottle three days later and it's like opening it for the first time.

Easy to use and great for anything with bubbles. I like prosecco but only a glass or two. This saves the rest of the bottle without it losing it’s effervescence. I ordered a few extra to give as hostess gifts.

Easy positive action for sealing and unsealing. Seal is very tight. Good design and usability. Reasonably priced.

I've been using this for a year now and this thing works perfectly. I don't think any gas leaks out at all and the cap stays right in place despite the pressure in the bottle. I use a lot of prosecco bottles to make spritzes for one person, so I'm not using a lot of sparkling at one time. This device allows me to get the bottle to extend its use a week or two. Naturally, as with any carbonated beverage, this is not going to combat the empty space in the bottle that gas releases into as you have less and less liquid in there, so it won't taste brand new when the bottle is half empty (just like soda bottles), but it's as good as you're gonna get and no gas is leaving the bottle itself. I highly recommend this.

Item is as advertised, seems sturdy but only time will tell

The champagne stopper works great! It keeps the bubbles bubbling!

Hervorragend, dichtet 1 a ab , selbst wenn nur noch wenig in der Flasche drin ist und man öffnet die Buddel erneut nach einer Weile, dann zischt's richtig. Habe mir gleich noch einen bestellt.

Great champagne stopped very good quality and well made design. Would highly recommend.

Seems to work great for keeping the bubbles in the prosecco

KLOVEOのシャンパンストッパーを購入して使ってみたところ、「もっと早く買えばよかった！」と思えるほど優秀なアイテムでした。イタリア製のしっかりとした作りで、特許取得済の密閉機構のおかげか、炭酸の持ちが抜群。翌日までしっかり泡が残っていて、開けたてのような美味しさが楽しめました。 これまでいろいろなシャンパンストッパーを試してきましたが、どれも翌日には泡が抜けがちでがっかりしていたのですが、KLOVEOは全然違いました。圧力ポンプも不要で、ただ差し込んでロックするだけのシンプル操作なのも◎。おしゃれなデザインも高級感があり、ギフトにもぴったりです。 正直、価格は少し高いと感じましたが、それ以上の満足感があるので納得しています。週末に妻とスパークリングを楽しむ我が家では、もう手放せない存在になりました。

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.
