Funcionan muy bien, preservan un poco mas el gas del vino espumoso.

LOVE IT. I never thought two stoppers for $15 would change my life like this. I originally bought them as a Christmas gift for a friend who told me she drinks less champagne now because she often wastes half the bottle when she cannot finish it on her own. Someone had mentioned a newer type of stopper that also removes air like wine savers, but designed for champagne. So I searched on Amazon and came across these. Wow, they work incredibly well. They worked so well that I ended up buying a set for myself too. These are nothing like the old traditional stainless steel champagne stoppers. The bubbles were still very present even the next day. They clip on very securely at the top, and it's leak-proof (although I would not recommend laying your champagne bottles horizontally, as the next time you open them it can be quite "explosive", as with any type of bubbly liquid). IMPORTANT NOTE: these are not for wine! They do not fit wine bottles at all. This is really a product made specifically for champagne and sparkling wines. I definitely recommend this product!

Amazing – if I could give it six stars I would. I don’t say that very often. My wife loves bubbly but we don’t drink much of it because the second day it’s flat and tasteless. Years ago we had a pumper that worked, sort of, but over time it wore out. With Christmas coming I went to Total Wine and asked what they had, to preserve bubbly - they said nothing. This shocked me. So I really dug in and looked at everything on Amazon, this one rose to the top. And it works incredibly well (so far) – I’ve used it with four bottles in the first month. You press it down securely then fit the “wings” over the bottle until they CLICK - it's very audible, you know when it clicks. Then you pump it up – which is really easy, doesn't take alot of strength. When the bottle is ¾ full I pump about 30-40 times, half full 50-60 times, and so on. A day or two later (keep it in the fridge) you pull the wings off carefully so it doesn’t accidentally pop up into your face (a problem with any champagne bottle) and then lift gently. It doesn’t just make a nice pop, it makes a gentle explosion, like opening a bottle for the first time! It holds serious pressure for days (as much as you want to pump) and the bubbles are perfectly preserved. I read many reviews before purchasing and one said that there are some bottle tneck ypes that don’t fit snugly, so he wraps a rubber band around the neck and it helps hold the seal. Haven’t had that issue so far because all of my bottles are pretty standard. A couple of times after putting it into the fridge early on it would pop, apparently I wasn't clicking it snugly. So I now wrap a rubber band around the wingsj just in case to hold them in, no problems so far. But if you are able to get the wings to click firmly it shouldn’t be a problem. It’s pretty well built but it is made with some plastic and some reviews said it can break. That’s OK, I’m just being careful. Nice that you get two units for the price. If after a year I have to replace one or both of them, it’s worth it in savings and in drinking more of what my wife loves. Give it a try.

I have used several sparkling wine preservers, including expensive ones with gas canisters, and these work as well. There may be a slight difference, but it's not perceptible. I wouldn't use this on your Cristal. I wouldn't leave it for a week. However, if you have a nice bottle of Cava, and you don't want to drink it all, this stopper works a treat. BTW it is NOT a vacuum pump. Why would you want that? It pumps room air into the void to maintain the sparkle. Significantly, for me, is the fact that there are no consumables - and those gas canisters are not cheap!

I never leave reviews, so this is special. We used this closure on a bottle of champagne. We kept it closed for about 2 weeks. We were shocked, when we opened it up, it was just like we had never opened it. It was fantastic. The key to it working so well is that it puts pressure into the bottle, which stops it from losing its' fizz. We absolutely love it! Note - this would not work for wine, because for wine, you want to remove the air, but for champagne, you want to add pressure.
