Review: Good value - Very nice bottle opener and it does seal the bottle well afterwards
Review: My lockdown workhorse! - This little thing has been getting a lot of use throughout the various lockdowns, more than I am proud to admit! And yet you wouldn't be able to tell, it's really sturdy and well made, hasn't dented/scratched at all. It's probably the perfect size to fit in your hand, openers that are too big or too small can make cracking a cold one a difficult task and it really shouldn't be. To be honest I only really bought it because I thought the bottle resealing feature was pretty cool and I could use it to stretch out some higher ABV stouts over a few days rather than having to drink all at once. I was surprised how well this actually works and have tested on a few opened beers in the fridge which kept for a few days before noticing any real drop off in carbonation and flavour. Impressive. Haven't tested the twist-cap feature and probably never will, I'm not a fan of Bud and while I think more beer should be twist-cap I can't see that happening any time soon. Overall I imagine this will probably last me many years and I would recommend without hesistation. Plus it's great value for money.

## Questions & Answers

**Q: Husband used this twice to reseal beer bottles, and both times top of bottle shattered after a couple of hours in frig. What is he doing wrong?**
A: Since metal contracts in the cold, sliding the sealer on as far as possible may be the cause as the steel contracts on the fragile glass. It just needs a snug fit versus a tight one. I've used mine that way for dozens of bottles with no shatter.

**Q: What's the difference between Original and Silver besides price?**
A: Silver is being advertised as the retro edition. Please visit the following:
Original: https://westmark.de/produktkatalog/en/bottle-opener-and-sealer-hermetus-61832270.html
Retro look: https://westmark.de/produktkatalog/en/bottle-opener-and-sealer-hermetus-retro-look-6183rt60.html

**Q: What's the difference between the silver and original finishes for sale other than price?**
A: I purchased the silver and it holds a shine similar to a stainless steel that has been polished. I assume the original finish is an unpolished metal.

**Q: Will this work for mountain dew bottles**
A: Yes.

This will work with any Mountain Dew bottle you have... glass AND plastic! 

It can pry off any metal cap.
It can screw off any plastic cap.

This opener/resealer ROCKS!

### ⭐⭐⭐⭐⭐ Excellent product, love it !!
*by E***E on 2 June 2024*

Very good quality, no bad surprises. Works exactly as needed. Very easy to use. A beer bottle still sparkling after several day using it. A bit expensive but worth the value according to me !!
