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

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!

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.

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

Great product, certainly keeps any sparkling wine nice and fresh.

This looks like a quality product and certainly with a price to match. It generally works very well but after using for a while I have noticed that if there is only a small amount left in the bottle, ie. One glass, it doesn't keep the bubbles in as well as when there is half a bottle left.

Very easy to use. Really surprised at the fizz retention. I left half a bottle in the fridge on it's side for several days. No leakage and fizz kept. Be careful I just released the clip and there was a very loud bang, hold onto the top and release slowly. Very good product.

This is an outstanding bubbly bung. I’ve been disappointed with all the others I’ve bought in the past, and baulked at the price of this one, but it was money well spent. I was astonished to hear the ‘pop’ and see the bubbles when I pulled out this stopper the day after I’d opened the cava. I could have passed it off as a bottle which had just been opened. You get what you pay for, and here you are getting quality. I won’t revert to the standard type again, as the clip which holds the stopper on transform its effectiveness.

Perfect. Good unit. Tried it with a bottle of Prosecco, Cava. Next will be a bottle of Crystal. I am very happy and it does keep the fizz. I recommend it.
