if it's
the one I think it is then it's not gummy at all - it's a very rigid mouth guard and I don't like wearing it.
The one i like is
this one.
As a back up,
this one is also pretty decent.
I currently have one of each already boiled & fitted in my gym bag, though I tend to only use the first.
The gel nano looks pretty cool; but looks designed for someone with less of an overbite than I have.
The power double was the best double I've ever tried, but that's not saying much - I still don't like doubles and I really don't like rigid mouth guards.
EDIT: I go through a decent number of mouthguards myself. The gel max may start to break down if you store it in mouth wash or make the mistake of leaving gum in your mouth while wearing it; but replacing something that costs $10 every year or two isn't a bad deal.
