Review on 🏋️ Revolutionize Your Workout with New Age Performance 6DS Sports and Fitness Weight-Lifting Mouthpiece - Lower Jaw Protection - No-Contact Design - Complete with Case - Army Green by Darryl Blumenthal

I chose the army green 6DS over other colors because of the case. The case shown in the picture says "Full Combat Rumble" and something else. Anyway, this is not what appeared. It is simply written in capital letters 6DS. So if you buy it, be aware that the case shown is likely not the one shown in the picture. The fit is fine. I've been using the Nike Airflow mouthpiece for a year and to be honest I haven't noticed any difference. The bag reads "Expect the Difference" and "Undeniable Result". He also has a comparison chart between "New Age" and "Other" which doesn't seem very fair. In general, everything is fine, just expensive. Other less expensive mouthpieces will likely work the same way. And since they suggest you get one every three months, I'll probably buy a different one next time.
