★☆☆☆☆
Opens the mouth too wide and only works with front teeth
I think it would be more efficient if the molars were engaged in the biting process. With this product, only the front teeth are engaged which tires the jaw fast and doesn't feel like all the jaw muscles are fully at work. When you chew meat or gum your entire teeth are working, molars included. This product is not for me.
