I just got my opro back in from them.. it is finished and complete. Anyone who has thought about getting one of these over a boil & bite. DO IT! this thing is so much more comfortable. Damn i am impressed. It suctions to my teeth so that i cannot fall out. It isnt to long or a bit uncomfortable. It is short and doesnt bother my lips or the back of my mouth. I have to say.. after this i will never get another mouth guard except Opro.. and im pissed at my self for using a boil and bite for the last 8 months... thing has caused untold damage on my mouth.
