Jawzrsize Athletic Bundle Jaw Enhancer - Jaw, Face, and Neck Exerciser, Helps Reduce Stress and Cravings - Facial Exercise (Pop N Go & Custom Fit (Beg., Adv., & Elite), Green & Blue)

These things actually work. Defined my jaw by a lot. You have to be consistent with it. Doesn’t really help with puffy cheeks though.

You can feel the burn after a few reps. Easy to use and clean. Worth trying if you want to strengthen facial muscles.

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.

Awesome

The one that has to be boiled and formed to your mouth is terrible!!! The clear parts that form to your teeth just pop out every time you try to use it and fall out when you carry around. Forget about putting it on the necklace as you will lose those inserts!! How about some more necklaces too?? They couldn’t cost more than a few cents but you only get one. Bad value for the money when you can’t use one of them and the two easier ones are too light, no resistance.

Check my pics! These things totally work and fast! When you first start using it, the soreness is a bit of a doozy, but once you make it past that, it’s all downhill from there. This is actually my first time buying the total contour pack, but in the past, I’ve purchased these separately. I’ve been using mine for one year and yield these results. Try it today!!

You can definitely tell when you are using this. After the first couple days expect your jaw to be sore while eating. The different resistances are nice as you can slowly work your way up to the highest one. Easy to use while driving or sitting around watching tv.

Using it twice a day and rinsing and drying it each time, It cracked inside and I bit right through the blasted thing after a week…
