Good to have

I bought these hoping to not burn my lips on hot stainless steel camp coffee mug - they work great - good fit on mug lip, stays where you put it, somewhat affordable, and makes camping a little more enjoyable The con is that after my purchase, I bought a titanium cup and, since titanium doesn't hold heat the way stainless does, the cup is not hot enough to need this item and I don't really use them anymore If you're thinking about a titanium cup purchase, you might wanna rethink buying this item
