New Age Performance 6DS Sports and Fitness Weight-Lifting Mouthpiece - Lower Jaw - No-Contact - Includes Case - Black

Little expensive, however great product.

Great product, works exactly as stated. The benefits at the gym are awesome and I save my teeth from being chipping

I was skeptical at first.. saw an instagram ad or something so I ordered one. Doesnt make me any stronger, but it does feel really good to bite down. Definitely helps me focus on my posture more during the lift.

This thing really works! I lift heavier, aligns my neck, and strengthens my jaw. Also helped eliminate my sleep apnea.

Super Prost surtout pour la force strongman recommande

The product arrived prompt and complete. Test fit went well, but the process to mold had left it severely deformed compared to any photos by the website. I immersed it in the boiling water for a full 50 seconds, bit down, then cooled it as per their instructions. It now looks severely deformed, but that being said, it appears to work fine with no discomfort in the mouth. I will also say that it does appear to make a massive difference in the ability to bite down and exert more force while lifting, therefor making lifting heavier more attainable. One note tho, it does also feel like while I can bite down hard, that I may also bite right through it. Only time will tell.
