ZQuiet, Advance, Custom Anti-Snoring Mouthpiece, Adjustable Mouthguard with 4 Jaw Advancement Sizes, Slim & Low-Profile, Clear

The mouth piece was very blocklike. It did not mold well to my teeth at all and as a result was not form fitting. It slid around and fell out. Not a very tight fit at all.

It's a little costly but well worth it. I misplaced my guard and bought another one. It works great. No headache in the morning.

Was uncomfortable and didn’t stay in place through out the night. Company refused to return. Waste of money.

Impossible to use: Too small and not adaptable to my mouth under any configuration.

I had been looking at mouth pieces for a while, and my wife said "do something!". I am now on my third one of these and it flat works. I liked the design of this: its obvious how it works, it's fairly small, and it's not too expensive. It took me all of 2-3 days to get used to it, and it has almost eliminated my snoring. I've gotten to the point where I notice quickly if I forget to wear it. I did notice some tooth pain and what felt like slight movement early on. That has stopped. I also sometimes mouth-breath more which dries out my mouth quite badly, so I keep a glass of water next to the bed. Another small issue is that the molded inserts will detach from the base. A little super glue gel and that's fixed. I run spacer #2 and it works great for me. I'm 5' 11" and 190 so not obese. Highly recommend you try this if you snore.
