I've used and molded mouth guards for decades at this point. Never had too many issues with the old yellow and red ones that attached to helmets, but figured trying something new for my kids might be worth it.Man, mouth guard technically has dramatically improved. These things are awesome! My kids appreciate that they're a little thinner than the old style guards, so it's a little easier for them to talk while wearing them.Biggest benefit to this mouth guard? Easiest re-molding process ever. You know how your kids keep losing teeth? No problem! Just throw this thing in some hot water until it flattens out, then just re-molding it. I've used this mouth guard for my now 11 year old for 2 solid years. Re-molded it three times after losing some teeth and a growth spurt. Just fill the instructions, and be sure to at least give it a quick rinse in cold water before putting it into kiddo's mouth to mold.

It's really good. First mouthguard which allows me to somewhat hold a conversation

These are great as you can talk and rink with them in. My son would forget he had his in and great since he is a QB for calling plays/signals. The girls on my daughters lax team have been pulling out the old rubber ones and not wearing correctly and the refs would get on them about it now they all have these and no issues and the girls can communicate.

Not a lot of material to mould over the pre-molars and feels like just an expensive piece of plastic with a lot of marketing. Definitely takes a few tries to mould it snugly so just keep redoing it until it fits well. It is though much more comfortable and breathable than other brands. I used it for jiu jitsu and light boxing sparring. Definitely would get a much thicker one for heavy sparring.
