It broke after using for four days but I fixed it myself.

Used this for about a month, and noticed my jaw was getting tighter. I didn't know if this was good or bad so I asked when I saw my Doctor, and she noticed my face was becoming more WIDE. With this product, I was working out the masseter muscles, which are large chewing muscles at the side of the face. NOT GOOD FOR DOUBLE CHINS.I also felt that this product was making my teeth BUCK!!! Sorry, but if you want to lose the face fat you have to work out!//22 F

what a waste. The soft moldable pieces simply pop out when you bite on it. Don't bother.

just get the name brand

I bought this as a gag gift for my brother as he has no jawline. He says it doesn't use it but I bet secretly he does.

good jaw exercise. work s great so far. the first few days of using the product your jaw and face muscle will be very sore., but it will be fine. a little bit of overpriced. I used it almost a month, loved the results

To my great surprise, it really works! For better results needs to be used daily
