I got my Jawflex Exerciser after watching my sister using it. I find it easy to use. I have been using it for about a week now and I can feel a different already in my jaw. I will continue to use it and may update my commends later on the outcome of using the product over several weeks. I would recommend it. Read more
1. This thing will eventually get moldy and/or rusty and become unusable because after the first use my saliva was already stuck inside the metal springs (see image), and since the metal springs are covered with a clear plastic I couldn’t clean it unless I break it. So already it’s worthless. 2. They said there is no plastic taste but that’s not true, there is a definitely a plastic off taste, I had to brush my teeth and mouth and I still have the plastically off taste in my mouth. Very likely to have BPA or other synthetic chemicals but I could be wrong. 3. This thing has almost the same resistance as chewing gum. After only trying it once I easily did about 400+ reps and still didn’t feel anything. 4. It’s not comfortable. I have sensitive teeth and the plastic is hard for my teeth. 5. I already knew it was overpriced before I bought it but now after all these issues it’s more than just overpriced, it’s a complete ripoff!! I hope they rethink this product and come out with version 2 to fix all these issues but until then just don’t buy it. Read more

This works great but I put 3 stars because I purchase late April and it’s been about 4 months and it seems to loosen up and doesn’t feel like it’s getting the job done anymore. For the price I thought it would atleast last a year but maybe mine was just one of the few that don’t last as long. Read more
I bought this to get a better jawline and I haven’t seen anything yet but I’ve noticed after a week of use, my jaw muscles were hard as a rock. It helped me get ready for a tonsil surgery due to during the surgery they have your mouth stretched open and using the jaw strengthener i had no pain after surgery in my jaw Read more
I would recommend if you are seeking to exercise and chisel your jaw. Once you do it for a while, it will be like second nature and not hurt as much. After use, I do feel my jaw muscles kinda sore for a minute or two. It is kind of high in price but you do get what you pay for and this my friend is worth the money. Also, chewing a big ball of gum would be beneficial as well when added to your jaw exercise program. Read more
Almost broke my teeth trying to bite this thing, the resistance is not more than chewing a gum If you can chew a gum with your jaws little open you won’t need this! Read more
I purchased this product to reduce the appearance of my double chin and to give me a more defined jaw line. I’ve been using it for a week now and already see a difference. It’s very easy/comfortable to use. Highly recommend for anyone who has the same issue. Read more
This $5 dollar toy is clearly not worth the $65.00 I was charged. It's a cheap, plastic, made in China (i.e., super low quality), that looks like it will fall apart after one time use. I urge people to stop buying from Amazon, you see Amazon is mostly third party sellers who sell junk and mark up 1000 times in order to get profit after Bezos takes his 40% cut, so who pays the mark up...we do, consumers. I am tired of buying from Amazon, paying exorbitant prices for junk, and by the way, free shipping is not so free. I have often been charged hidden shipping costs third party sellers don't tell you about, but you find out after you were charged. Yea, and free shipping, not so free, and not so 2-days as they claim. I helped make Bezos the richest man in the world because I am just a dumb consumer who throws dollars away on his website that he scrounges to add to his trillions. The more I buy from Amazon the more I am disappointed. I am tired of Amazon tracking my every keystroke so they can collect my data and sell it to add to their trillions. I want to see the retail industry get back on its feet, time to ditch Amazon and its monopolistic empire. Read more
