Review on 🏋️ VEBUNI Jaw Exerciser: Define Jawline, Reduce Cravings & Stress, Chisel Chin - Slim and Tone Your Face for Men and Women - 3 Resistance Levels 40, 50, 60lbs - Restore Youthful Appearance by Holly Walker

I received this item today and followed this guide to fit it to my mouth. After 24 seconds of cooking the product, 15 seconds of biting off and cooling, the machine did not change shape at all. I've tried this several times with no success. When using the product, the protective teeth kept slipping out of the main body, rendering the whole thing unusable. If mouthguards were built into the machine itself, this WOULD be a useful product, but unfortunately it isn't. Overall I would not recommend. For $13 you can just buy a bunch of gum and train your jaw that way.
