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.

Fabulous design for an oral appliance… Fabulous design for an oral appliance to aide with sleep. Never slept better!

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.

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.

I’ve tried many devices all have failed… I’ve tried many devices all have failed my jaw. My mouth would open apart, and my jaw would fall back and I would snore Sleep MD device keeps my jaws intact with the wings, preventing my jaw to move backwards. It’s the best idea that I’ve tried it’s a real good working device I truly recommend it.
