I have had several of these mouthguard type of jaw exercisers, but these are definitely my favorite. I like how comfortable these are. With some other exercisers, I feel some discomfort in my teeth as I bite down, but I did not have that same feeling with these. This means I am able to do more reps. I am no beginner to jaw exercisers. I have purchased and gone through several jaw exercisers, even using one adjustable jaw exerciser that I turned the resistance up all the way to 130 lbs. That said, to make sure I got my money's worth and to try the product out fully, I decide to start with the least resistance each time I get a new jaw exerciser and work my way up. I am still on the blue one (beginner, 30 lbs) and will move to the 40 and 50 lb. resistance once the blue one becomes unusable. There are a few holes my teeth punctured in (to be expected), but it is still going strong. I think what really helps is the design here. There are lines, or grooves, at the top and bottom that seem to help limit damage to the mouth guard. I have went through devices like the Jawzrsize Pop 'N Go advanced green faster than the beginner blue jaw exerciser here, and these cost less. I also think these do better at sculpting the jaw and are easier to use because of the comfort they provide. Read more


I’m a petite woman and it makes me gag. My husband is also not feeling much when he uses it. Read more
This jaw exerciser set is nicely designed and packaged. It comes with instructions and three exercises, each in its own case. If you have a sensitive gag reflex, you might have trouble with these but there are holes to aid in air exchange if needed. I started with the lowest strength (the resistances are color-code with blue being the lowest), and I can feel that my jaw muscles have had a workout. I’m eager to continue using these and experience a stronger jaw. They are a universal size, and will probably fit any adult. I wish they made them just a wee bit smaller for adults with small mouths. The instructions have a QR code to a video with more instructions. The storage box is nicely designed, with a magnetic closure in the lid. Overall, I am pleased with these. Read more
Not even a month of buying these jaw mouth guards, they are broken and useless. It's not worth buying this product. It doesn't do much. They rubber is not that thick or strong to work with consistently. Waste of money. Read more

The packaging of this facial/jaw trainer is pretty nice. I have been using this now for about 10 days and it was about the 5th day I noticed that it was toning my jawline. I didn't think it was going to work. So, I kept going just to make sure I wasn't imaging it. This set works. It feels strange at first but I followed the directions to a T and am seeing results. I suggest to do it in the evening while watching tv, crocheting, or reading a book - that's what I did. I have to admit I am impressed and will continue to use it. Very very happy! Thank you!

These seem to do their job. Holding up, not breaking down. Not too much to say about them Read more
