Jaw Exerciser for Men Women Jawline Exerciser Jaw Toner with 3 Resistance Levels, Silicone Jaw Trainer & Jawline Exerciser Shaper For Beginner, Intermediate & Advanced Users, 6Pcs

These come in three different resistance levels - I used the easiest (white) and I can definitely feel them giving my jaw a workout. While it is definitely too early to tell, these are an inexpensive set of exercisers to try out and I am optimistic, based on the first few uses, that they will be effective.

Honestly I feel like these are a good product but worry they are an accidental choking hazard.

These are great for exercising your jaw. I wish they were a little bigger, but they get the job done and give your jaw a good workout! I have used them two different ways so far; by placing one on each side of my mouth and another by placing one in the front then biting down. After the first use, my jaw was sore, but using them gets easier over a period of time. I recommend going slow and taking your time kind of like chewing gum. I would get them again; I can't wait to see the end results.
