JawzrsizePop 'N Go and Custom Fit Jaw Enhancer - Jaw, Face, and Neck Exerciser, Helps Reduce Stress and Cravings - Facial Exercise (Beg., Int., Adv., & Elite - Blue, Pink, Purple, & Green)

I've started with the beginner exerciser and that really works. I have TMJ and I was hesitant if this would make my jaw pop a lot and it doesn't pop at all. I can feel the muscles being worked out very well. I'd definitely recommend this.

Unfortunately, I received damage silicon necklace strap.

Si es efectivo, pero muy caro para lo que hace

The squeakiness of the rubber is intolerable.This device works no doubt. I've noticed that I have a sharper jaw line after several weeks of use. Unfortunately, there's a small removable piece that conforms to your individual teeth that has become loose. This small piece is attached by only two small anchor pieces of plastic so there is no robust attachment point.I purchased the four-piece kit for $45.98. I'm somewhat happy with the kit, but there are definitely areas that can be improved. For one, a more pliable and pleasing type of rubber that doesn't squeak during the "chewing" motion. And there must be a better way for the area that your teeth sink into to be more robust to where it doesn't fall out during your jaw exercises.I have mixed feelings on this jawzrsize device. It's not cheap at almost $46.00. The quality is not what it should be. It does work, but there are sacrifices when using the device such as major squeaking (which drives me crazy).I can only rate this item three stars and don't recommend it due to durability issues.

I tried it but my teeth end up a bloody mess. All my gums start bleeding, and I don’t have cavities or bad gums or anything… so I was too concerned to keep trying this product
