This is the best mouth guard I've ever used. To be honest, I never really liked the feel of a mouth guard because it always made me want to gag and made it harder to breath. A bunch of the guys at my gym told me to try to this one, and I am really glad I did. The molding is easy and actually works, and it's got a really nice fit. I've gotten other mouth guards where you have to try to mold it to your teeth several times and it never fits quite right. Also, with this one it's definitely easy to breathe. But best of all, it's effective, and you can really take some inadvertent hits to the face without messing up your jaw.

Another really cool feature is the one-year warranty against defects. Basically, if you are wearing your mouth guard during a tournament or coach-supervised training session and lose a tooth anyway, they'll actually pay for your dental care. I don't expect to lose a tooth doing jiu jitsu, but it's nice to know that they stand behind their product.
