Bests & Worsts Reviews from Amazon

To anyone out there purchasing this with the idea of trying to strengthen and define your masseters (Jaw) Its a waste of money compared to the alternative options which the best of is mastic gum. So much cheaper then this A and B is SO much more affective due to the fact that it allows you to bite down directly on your molars rather then from your front teeth, which is honestly the biggest design flaw in this thing. Jawzersize is a complete and total ripoff that sells itself off of bright colors and ease of use but really will deliver minimal results. Youre much better off getting mastic gum off of amazon. Take my word for it youll save 40 something bucks.
