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 Rob Dixon

I was really hoping this would work but after following the installation video and submerging the mouthpiece in hot water for 50 seconds, the mouthpiece became too soft and twisted into a pack of gum. I tried to warm up and adjust, but too late, it became useless. Not sure if I did something wrong, or it's just too hard to combine. The website says that you can return it after 30 days if you are not satisfied I hope they keep their word and accept my return I would appreciate any advice on how to get the right device as I enjoy using this device.
