Ya know what...maybe Doc Brown from Back to The Future should do a test on The Rock Jaw. The sales would increase.
Or...I can spar with The Rock Jaw haters and we can find out who has a better chin. I've been using it for 2 months, 165lbs age 39 in Deltona Florida. Lets do the test with some 10oz gloves and no head hear.
Mail me and come find me.
Sparring wont prove shit.
We all know your product helps the jaw...LOOK AT VICTOR ORTIZ he broke hsi jaw in a fight.
We need you to stand with an open mouth and let a pro hit you with a haymaker , so you can show us that it works !
