Item works as intended. I waited a week to leave a review, but the item does work and I see improvements in my jaw line. These other low ratings are all about it being a choking hazard do not listen to them. If you’re old and a young kid, yes it can be, but if you know what to do or how to use them then it won’t be a choking hazard. I highly recommend buying this and when you want go upgrade. These are great starter jaw like exercises! Read more

While I'm not 100% sure how effective jaw exercises are, I am very happy with these resistance trainers. They are very well made and the silicone has no taste that I've been able to detect. They're super easy to use and are durable enough since I've been using them every day for 3 months with no visible wear and tear. I think they're a good value if you're looking to try them! Read more

I wasn’t sure what to expect at first, but this jaw exerciser really works! The silicone feels comfortable, and the four resistance levels make it easy to progress gradually. After using it a few weeks, I can feel a noticeable difference in jaw definition and strength. It’s also oddly relaxing to use while watching TV or working. Read more

These might work well for men, but for me they were much too big and difficult to actually utilize. Once I got even one of them in my mouth, there was no room for my jaw to exercise. Lol major deterrent for me, I only tried them a few times and then didn't have the desire or motivation to continue making an effort. Read more

Beware these are a choking hazard before considering using! It takes some getting used to and I gagged the first few times of using them. I don’t think these are meant for smaller people as they take up practically my entire mouth. The lowest intensity is 30 pounds which seems like a lot to be the lowest. I have yet to try any of the others because 30 pounds tires my jaw out fairly quickly. I have not noticed a difference in my jaw line either after using for a week. Each set comes with their own case so you can easily tote them around. The silicone is very durable and even with consistent use, they still feel like the first time I used them. Three stars because of how they are designed, they are definitely a choking risk and should be cautiously used. Read more

Very tough jaw exercises built to last. I found my muscles felt the resistance after 3x8 reps with the grey ones. Read more

As I get older, I have loose skin under my chin and jaws and I really wanted this to be effective. These go between your molars and you bite down to exert pressure on the rubber pieces. The very first thing that jumped out at me is trying to keep both in place at the same time, I almost swallowed one. These are not a flowing piece of rubber, they are square with defined corners. If you swallow one, it will get stuck in your throat and you will choke. I wanted to be thorough, so I continued to test these. The next thing that jumped out at me is that when I bit down, these seriously aggravated my TMJ (clicking jaw). If you have TMJ, avoid using this. I think with continued use, this would strengthen your jaw muscles, but the choking risk and aggravating my TMJ are serious concerns. Read more
