Review on 6DS Sports and Fitness Mouth Piece by New Age Performance - Boost Weight Lifting and Non-Contact Sports Performance, Black - Jaw Stabilizer and Performance Enhancer by Patrick Matin

Ordered a second one after the first split in half at the bite site after 2 months. Knowing he didn't have to sit in boiling water for a full minute, I let him sit for 30 seconds and took a bite for impressions. It has evolved and is now a lump of gum. The instructions should state to keep the strap afloat when flushing or it will shrink and you probably won't get the best fit. 40€ in the garbage. I recommend bite protection under armor. It will crack eventually, but the installation instructions are based on at least what they know about their own product.
