Review on Keystand Mouthpiece Professional Mouthguard Basketball Sports & Fitness for Team Sports by Michael Tarlue

These are literally the worst quality mouth guards I have ever had. They break (in several places - see picture) as soon as you put them in your mouth to shape them. It was a set of 2 and both broke right after casting. I wouldn't waste your money on them like I did. It's expensive enough to just send your child to a soccer program! We've had other mouthguards that we've had to replace, but never anything like this. They didn't even come with instructions.
