Description
Has 3 units with 3 different levels.  I have personally used these and can vouch for them.  There are also several youtube videos demonstrating its effectiveness.

Also helps with breathing and can reduce the need for teeth braces as it does widen the jaw.  Has its roots based on Smart science.

Features:
1. Our jaw exerciser will apply pressure to your posterior teeth, increase blood flow in the masseter area, exercise the masseter muscle through occlusion, consume excess fat, and help you shape your jaw lines and face shape.
2. The set includes three stages of 40LB/50LB/60LB, and you can gradually adjust resistance based on the accumulation of training time. You only need to do 5-10 minutes of chin exercise every day. If you persist for 30 days, you will find significant changes in facial lines.
3. Using a jaw trainer to exercise the face not only helps improve facial shape, but also helps to enhance facial skin vitality, reduce wrinkles, and avoid skin sagging, making the skin tighter and more energetic. It is suitable for both men and women.
4. The material selection is safe and environmentally friendly food grade silicone gel, non-toxic and chemical free, durable. Our jaw trainer can be easily cleaned with water and soap.
5. The jaw trainer conforms to the human oral structure and is suitable for adults. It is compact and portable, and the set includes a storage box, making it easy to carry. You can use it anytime, anywhere.
