Review on 🏀 SISU Aero 1.6mm Sports Mouth Guard: Perfect Stocking Stuffer for Youth and Adults Playing Basketball, Soccer, Hockey, Lacrosse by David Elam

Do not use for Jiu-Jitsu or other forms of grappling. The material is so hard that I felt it wear down my gums to the point where my gums bled in many places even though I molded them to perfection. In use it feels hard as stone and if you wash it with warm water in the sink it completely loses its shape (hardly any hot water). It's nowhere near as good as the softer forearm guard that my dog ended up eating. I will try to find it again. I gave 2 stars because it couldn't be molded. This can be useful when gardening or other safe activities.
