Review on 🤼 UROKAZ Football Mouth Guard - 5 Piece Set for Enhanced Sports Performance in Boxing, MMA, Basketball, Lacrosse, Muay Thai, Hockey - Universal Fit for Contact & Non-Contact Sports - Mouthguards for Maximum Comfort & Protection by Francisco Yim

I bought these for my 9 year old to wear while sparring in karate class. He loves the feeling and it encourages him to wear it which is great. Note that it will shrink a bit if dipped in hot water to try on, so be careful not to cut too much before beginning this process. Unfortunately we lost one the hard way but we had two others for the price of one elsewhere. It's nice that it comes with a case as he sits next to his sweaty gear. We haven't tried the other options so there's no direct comparison, but I like the cost, that it's comfortable to wear, and that it's silicone-based rather than hard plastic.
