Jawzrsize Pop N Go and Custom Fit Jaw Enhancer Bundles- Jaw, Face, and Neck Exerciser and Toner (Custom Fit & Pop N Go Pink Bundle, Pink)

Have only tired the smaller size of the two, but it works my jaw. I have very bad painful TMJ issues so I bought this to try to strengthen my jaw alongside of splint therapy at night. The only thing is it activates my gag reflex after not very long of using so I have to quit as soon as that happens

If you have sensitive teeth, be weary. Everytime I use it, my gums bleed on the bottom. But it does work.

I haven't been using this every day, but I can say I've noticed that my facial and jaw muscles are strengthened and my cheeks are more indented under my cheekbones.

It seemed to be working, providing some definition to my jawline, but they’re not very durable. I started with the pink one, and noticed after a few uses it was pushing into my gums. My teeth were cutting into it and sinking too deep. The blue one held up a bit longer, probably about two weeks worth of use but it’s been pushing on my gums as well. I like the results, but can’t afford to keep replacing them every few weeks

Although this made my jaw move more easily, the smaller one (not the one you are supposed to boil to fit to your mouth) broke on one side 2 weeks ago, and I only bought this at the end of September. I still use it, but of course it doesn’t fit right anymore and I don’t know if it does anything in a broken state. I am going to switch to the other one, but who knows how long that will last?! Also, I don’t notice any change in my jawline.
