CoravinModel Two -Wine Preservation System - Bottle Opener, Needle Pourer, Aerator, and Wine Saver - Graphite - Includes 2 Argon Gas Capsules and Wine Needle

Fantástico producto para no tener que abrir nótelas de vino y que no se terminen en ese momento o que si alguien descubre una botella en tu cava que no querías abrir, le compartas 1 copa, pero también felicito al proveedor que me lo envío, excelente servicio, muy rápida la entrega y solución inmediata

So easy to use. I can now have one glass of an expensive wine and save the remainder of the bottle for another day. Game changer!

Seller was honest, reliable with good follow up.

酸化しないのは本当に良かったです。　最初に使用した際セットしたボンベをケースから外してしまいガスが全て抜けてしまいました。

Since I rarely drink more than a glass or two of wine, I didn't like opening expensive bottles. With any other system, the wine falls apart after a few days. And Port is especially prone to an early death if not drunk witin a day or two. So, after seeing ads for this gadget, I finally dropped the $200 and waited, somewhat skeptically, to see how good it was. The answer: It's perfect, easy to use and clean.It goes through the cartridges pretty quickly, which is another expense, and I guess you know you have to replace the needle when it stops working as well--as in the cork doesn't seal itself and wine will leak out. However, I recently discovered that when you do get a leaky cork, if you just wait a few minutes, it will seal itself and you lay it down horizontally.Solved my problem of opening an expensive bottle for just a glass...or getting a glass from two bottles to compare.Update: After 5 months of loving this device, it stopped working. I called Coravin and got a human being on the phone in no time. He not only fixed the problem but sent me 3 free capsules because I'd gone through a couple that didn't work. A week later, it stopped workingagain. I called, got a human being, and after a few questions, he said the machine was probably leaking and he'd send me a new one. Since they don't make this model anymore, he's sending me a later one. No hassle. Great attitude. Makes this invaluable device even more valuable.
