I'm not a doctor and I'm not going to pretend a ring is magic. What I can tell you is what changed for me and for the men I handed one to.
The headaches that used to run my evenings got smaller and rarer. The pharmacy stopped being a monthly stop. My daughter started telling me about the frog kid at school again because I was actually in the kitchen to hear it.
I almost didn't buy it on principle. I'd just spent $1,200 on a tooth and the idea of a $29.90 ring fixing what a neurologist couldn't felt insulting.
The only reason I tried it was the 30-day return window. If it did nothing, I could mail it back. I didn't mail it back.
The reviews below aren't from me. They're from the guys who found the same thing.
Different ages, different jobs, same jaw, same 5 years of being told it was stress.
Read them, then decide.
