I enjoy this product, not worth 50$ but it’s very very useful. I’ve tried mastic gum and I prefer this over it. Nice and easy to use, can make you gag if you don’t know how to use it at first but then it’s easy to use. I’ve only used for about 2 hours max altogether and it already tore. Depending on the way you chew will break it. You should just be chewing it up and down. I reccomend this because you don’t use your cheeks to move it around, and when I chew gum I have to use my cheeks to keep in place and then after an hour of chewing gum my face looks swollen but with this my cheeks are this and my muscle is wider. I would definelty reccomend but it sucks it does tear. Also, this is the hardest one and it isn’t hard at all for me. I wouldn’t recommend buying the entire pack and I would just buy the hardest one.

I've been using this product for about 20 days straight. It got easier as I progressed but I'm not sure if my jaw has gotten stronger or if it's gotten easier because of the large cracks/splitting of the rubber. This product was great for about a week and a half. Now I feel like I'm accomplishing nothing.

Didnt last more than a month before they became damaged and unusable. Product was good while it lasted though

Got these after looking at the reviews and it seemed promising since i have been using a cheaper alternative (which i've had those for months with no damage in comparison) . After about 4 weeks of use they are already split. very disappointed with these.

I like the concept of excersising your jaw, however, I hate that the product is weak and breaks easily. I bought Chisel twice and twice one of the bites cracked. Don't buy until they make it stronger. The rubber material used cant resist jaw pressure for long. Mine cracked the same day I used them. Smh.

After 1 week this fall apart def not worth 43 bucks if you have to keep buying them every 2 weeks or so. Can you imagine having to buy lifting weights for exercises arms every 2 weeks cause they break no thanks

The product seemed to be working which is nice, but around week 4 the product started to break which decreases the resistance and then becomes unusable.

Add my name to the list of reviews that experienced product breaking. Great concept and idea to workout the jawline, but they simply didn't last. The set I got made it to week 2, but then tore. Not close to the expensive price.Look elsewhere and you can get a set of 3 different level jaw exercisers that are better quality for about half the price.
