Westmark Germany Hermetus Steel 3-in-1 Resealer Beer Bottle Opener

No complaints whatsoever. Seals the beer perfectly. The nature of the device is that as you pull and twist it along just a bit - very easy to do - a dense kind of rubber surface is forced against the top of the bottle, creating a perfect, solid seal. And I do mean solid. Complete and unshakeable. German engineering and simplicity.The device is also a bottle opener, which may not seem like much, but it's an excellent and satisfying opener to use. And then instantly, the bottle is sealed any time you want it to be. And by sealed, I mean perfectly. Absolutely perfectly. You could shake up as much as you like and nothing is coming out. You can toss it as far as you like, and if the bottle itself doesn't break from the landing impact, the thing is sealed as tightly as it can be.I cannot imagine how this item could be improved. Over time, the device kind of opens gradually from the pressure of twisting it on - but hey, German engineering: they've accounted for that by making the thing get narrower as it goes along and the device just makes the same seal further along. I've had them for longer than I care to say, and the older ones seal at a different point than the new ones, but the older ones aren't going to stop sealing because the way it narrows - you'll realize what I mean when you get one, just moves the sealing point a little further down, and clearly the end is so much smaller than the top that it's never going to reach the point where this thing doesn't seal.If you're looking for the total, complete resealing solution, this is the BMW, the AUDI of resealers. A whole other level than the simple ones of various kinds.If I keep going I'll just end up repeating that it's absolutely perfect for what it is: a beer bottle resealer.

I couldn’t find the right size bottle stopper for my Sparking Cider. I called Martinelli directly and the rep told me to get this one because it fits their bottles. The design can fit multiple size bottles because of the wedge shape on the underside and you slide it onto the top of the bottle from the side to cap it, for an airtight seal. There is no stopper that needs to go inside the bottle, this is entirely different and simple to use. Hope the photos help.

Having tried other types of stoppers, finally found one that works. Beer or other fizzy drinks can be saved. Just wish they made this in a larger size that would fit bigger bottles.

Coolest little thing I ever bought

Little tight for twist off bottles. I pulled the silcone pad out, used a strong pliers to open up just a tiny bit on the wide end, and put the silicone back and it works perfect now without having to force it.

Rocks it!!!

Es un producto alemán de excelente calidad.

This is such a simple idea, it should be everywhere. Any time you're not pouring out the whole bottle at once, this is the quick and easy solution.
