Don't recommend, primitive construction, very odd shape First, this product did not work for me. I have tried a few different products that work amazingly well. I do NOT recommend this item; try another less expensive alternative. Second, when you see the item, it will be very odd looking. Unfortunately, this product is primitive; metal pieces stick out on the sides and are uncomfortable. A clear, easy-to-use tutorial video is available to ensure accurate molding occurs, however, NO amount of adjustment can fix the protruding metal things. These wide metal pieces on the top are needed for the plastic triangles on the bottom piece to slide up and down properly on the upper. Although the lower piece with its triangles is adjusted to keep the points from stabbing the cheek, the two parts can clack together during sleep. Your partner can be more irritated by the clacking than snoring. The small is quite wide in the cheeks, and I found it to really bother me the entire two weeks I attempted to wear this appliance. Unfortunately, the company only supports using the odd-shaped appliance in certain instances; using the very detailed self-help video provided is not an approved method. I hope this review is useful to future customers.

Always helpful I replace my guard about every 9 months. They just get old. As always the Doctor and his team were excellent. The instructions are easy to follow and they’ll do a virtual fitting as well. John C

It does the job. It does the job. I've seen improvements to the design over the years. The video assisted setup/molding process was helpful. I always use the maximun lower jaw forward setting as I snore heavily, but this does inevitable cause the wings to come lose or the side metal things to pop out. But a quick molding of extra material and some patch work n it usually is good for a while. I've tried a few diff mouth devices and this is the one for me..will always continue to buy.

The mouth piece is very large The mouth piece is very large, but it broke and they never sent a replacement. Very expensive for a failed experiment.

Really helps me get a good night sleep. I've been using Dr Hamburg's device for many years. In my opinion, it's extremely helpful in getting a good night sleep. My wife also uses it and feels the same way. While they may be a little more involved to set up than similar devices, they are much more effective, comfortable, and have a secure fit. The upper and lower parts are separate which allows my jaw to move which makes it more comfortable for me. Remember you can make adjustments after the initial setup to get the most comfortable fit. I keep any leftover molding material as it can be used for future adjustments or repairs.
