Bests & Worsts Reviews from Amazon

I'm perfectly satisfied with this mouthguard. I read a number of the one star reviews and can say with a high degree of confidence that the problems they experienced were due to user error. For example, people mentioned the mouthguard collapsing after being boiled. The directions are very clear that you boil the water, REMOVE the water from heat, drop the mouthguard in for twelve seconds. I had zero issues forming my mouthguard. Some others said that the mouthguard could only be molded once. Again, not true. I actually re-heated and re-formed mine three times without issue.
