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

This is the fourth different mouthpiece I've tried. I think this is the one I'll stick with. The original ZQuiet didn't mold so it caused tooth pain. Another was too thick so my mouth would not stay closed. SnoreRX wouldn't stay put. This one meets all the needs. It took a little while for my tongue to get used to it but that is not bad.

This device is EXTREMELY uncomfortable. The mouthpiece itself is way to thin and squeezes gums to the point where even if I fall asleep with it in, I’ll wake up an hour later with drastic soreness in the gums because they’ve simpley made the hard plastic walls on the edge of the molding WAY to narrow. It feels like this was made for a child’s mouth. It doesn’t stay in place and DRASTICALLY reduced the quality of my sleep while also not really doing anything to eliminate snoring. This product was a complete waste of almost $100

Works great for my situation. I’m not sure what some folks are doing, but if the device fits in your mouth and you follow the instructions, it’s really easy to get a good fit. I didn’t experience any of the problems some reviews had. I’m adding this review after 7 months of use, and I can say it’s a good quality device that did what it said it would do for my type of snoring. You really need to read the info on their site that explains what it solves for before you buy it.

First let me say I have been using several different anti snoring devices for 10 years. Some better than others. This one is AWFUL. Difficult to fit, difficult to change side pieces, the tabs that stick out on the sides cut your cheeks. By far the worst product I have ever tried. Hard do not buy. At least it is shipped in a nice box.

I was excited to get this but sadly this didn’t help my snoring. I still snore while using this. I went ahead and use the highest level which is 4 and I still was snoring. I’ve been trying this for a month now and it doesn’t work. Don’t waste your money.

Decent but side arms break off easily.

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.

Just bought this after my original (custom made) appliance failed. This didn't work at all! To start, the hinges are positioned incorrectly for this to work properly. The hinge attachments on the upper plate are at the BACK of the plate, and the attachment for the lower plate is located at the FRONT of the plate. This leads to the top plate PULLING the appliance backward, which you avoid when snoring, instead of PUSHING the appliance forward, which is how these types of devices are supposed to be designed to do. Since the purpose of this device is to pull the lower jaw forward, this is physically impossible with the placement of the attach points. 4 sizes of bands are provided, and it comes with the shortest bands in place. Problem is if you use longer bands, and use the device as intended, the lower band is PULLING the upper band forward, off the upper teeth, making this device useless. I tried turning it upside down, which places the bands in the correct position to PUSH the lower jaw forward, with the top plate stabilized on the upper jaw, and it worked one night, but I need SHORTER bands to pull the jaw forward in that scenario, and you don't have shorter bands with what they send you. Waste of money for me...
