Takes practice but it does work
Edited after 2 weeks. Originally: Not so good for me. The jaw exercisers are bulky in my mouth and I noticed it’s difficult to swallow so I am drooling while using this. The other device doesn’t work. No matter how hard I try, I have to push the “ball” back into recessed position. I’m struggling to make this work but I may have gotten a dud. Update: after daily efforts and manually pushing the dome in and out it has suddenly become more pliant or else I have gotten stronger. It really gives you a workout. I’m more enthusiastic and optimistic. Good luck and don’t give up! Read more
