HYZ 2-Pack Champagne Stoppers w/Airtight Seal, Stainless Steel, Rose Gold | Silicone Sealed Sparkling Wine Stopper Keeps Bubbles Fresh for Days. Wine Saver Fits Prosecco, Cava & Champagne bottles

Easy to use. I opened a bottle of champagne on a Friday and drank half of it and used the HYZ Stopper. When we opened it back up a week later the bubbles were as vibrant as when the bottle was opened a week earlier.

These champagne bottle stoppers are the best. They hold onto the bottle and stay in place. Love them!

Nice quality

Keeps the bubbles in the bottle! Great champagne stopper. Great hostess gift., too...always keep a couple on hand for that. Previously shipped in individual boxes which was so nice when gifting. Sorry that's been discontinued but will still purchase. Took off 1 star for that reason. Also keep one in my "to go bag".

These stoppers are well worth the money because they hold carbonation well. Easy to place on bottle, too.

Realy like this product locks in place and works well

They really work

I've had many champagne stoppers over the years and they've always been fine, but never make enough of a seal with the bottle to prevent the champagne from going flat after 12-24 hours. You can imagine my shock to open one of these stoppers after the first use and have it pop like a cork because of the pressure behind it. It works so well, it kept one bottle of champagne bubbly and tasting like it was newly opened for 3 days. The silicone stopper is shaped like a cup and sits inside the mouth of the bottle, this helps seal the bottle better than the other models (see attached photos). It is easy to wash after use. The trick to getting a good seal is making sure to press down on the center button as you close the wings to cup the bottle. To make sure that your stopper doesn't go flying when you open it (like it did to me once!), make sure to push down on the center button as you lift the wings and slowly release the pressure.

So much better than what I was expecting!! They don't not feel flimsy. As long as you do not use them as a bottle opener

Very impressed with this top, it fits brilliantly and you can tell by the way the prosecco fizzes on opening it again the next day how it has preserved the bubbles.

These are great stoppers for things like champagne, Prosecco, wine, and more. The design is clever which means the product can be used on a variety of bottles. Perhaps the most satisfying part of this purchase is the “pop” you still get when you open bubbly that has been corked in the fridge for a week. I’ve only needed one, so this is a great pack to share one with a friend.

It works in sparkling wine, keeps the bubble a day or two, haven’t try it more than 3 days. It’s leak-free for the Prosecco I’ve drank. However, it doesn’t work that well on red wine bottle, it couldn’t lock for sure, so I don’t even bother to test if my red wine will leak. My conclusion is, it works, worth the money, but it’s not universal and really depends on how’s the bottle shape.

J'ai ouvert un champagne, bue la moitié et refermé avec un de ces bouchons. J'ai ré-ouvert cette bouteille 24h plus tard et c'est comme si je l'avais ouvert une première fois avec le bouchon de liège. Ce produit est génial et mon champagne même après 24h n'avait rien perdu. Je recommande fortement!
