              The PX2 has been awesome so far. Easily formed to my teeth with the included instructions. I have been using the PX2 primarily for weight lifting. I like how the mouth piece attaches to the bottom teeth. This allows me to breathe easier during strenuous workouts. Noticeable difference in less jaw pain and tension headaches when lifting heavy weights. Very happy with my purchase of the PX2 three pack. Good to go for quite a while now!
