I’ve only been using this for a couple of days, but I can already tell this thing works. The biggest surprise so far is how much it’s helped with neck tension and pain — I actually feel looser and more relaxed in that area after each session. As for the jaw workout, wow… you can definitely feel the muscles firing that you never knew needed exercise. It’s kind of wild realizing how much your jaw has been “out of shape” until you actually work it. The resistance feels solid but manageable, and after a few sets, you get that satisfying post-workout burn. Too early to say how much my jawline will change, but I’m already impressed with how it makes everything from my jaw to my neck feel stronger and more supported. Highly recommend if you’re curious or deal with jaw tightness, tension, or just want to try something new for facial fitness. Read more

I bought the Beginner Strength product. Chewed through it in less than a week. I suppose that means I should have gotten the Intermediate or Advanced product. I'm not sure about the durability of these things, especially at this price. It works though. Read more

Great design. Works all of the facial muscles. I bite with my mouth wide throughout the exercise (insert teethy emoji) for maximum benefit. Many foods in the USA are soft and hyper-palatable and this does well without me having to chew a lot of nuts and veggies. Read more

I just purchased my 4rth one of these (over like 3-4 years), if you have strong teeth with a modestly sharp edge on any of your front teeth, like me, then you will probably chew through this item in a few months, maybe less. I just get the advanced pop n go, as it last longest for me. It will work well while it lasts, and you will likely get some nice compliments, as well as better blood flow, definition, bone density and stress relief in your face. I wish they could thicken up or reinforce the contact points with the user's teeth, and release a new model for us 'chew-throughers'; I'm not the only one who has this problem. Read more

Before I used it, I consulted with My doctor and he said to beware of item because it can create TMJ or worsen grinding. So I returned Item. I found out it is not “prime” They charge $7 for return shipping. The item wasn’t even removed from the package. Please be advised that they are a shady company. Read more

I've always been a bit skeptical about products that promise significant changes to specific aspects of our physical appearance. However, after deciding to give the JawRSize and King Maker combo a shot, I am genuinely stunned by the results. First off, the JawRSize is a game changer. Not only does it provide a unique workout, but it's also oddly satisfying. It's like a gym session but for your face! Within just a few weeks, I started noticing a more chiseled and defined jawline. It's simple, portable, and efficient – you can literally exercise your jaw while watching TV or commuting. The material feels durable, and it's easy to clean, which is a big plus for me. Now, onto the King Maker by Top Shelf Grind. I was looking for a natural testosterone booster to complement my workouts, and this product caught my attention. The ingredients seemed potent, and the reviews were promising. I've been taking it consistently, and I've not only noticed an improvement in my jawline but also in my overall energy levels and mood. It feels like I've unlocked a latent potential inside of me, like a king ready to claim his throne. While individual results may vary, the increased testosterone levels from King Maker seemed to enhance the effects I was getting from JawRSize. Combining the two products was a masterstroke for me. The synergy between jaw exercises and boosted testosterone levels really delivered on the promise of a sharper jawline. But beyond the physical aspect, I also feel a heightened sense of confidence – walking into a room feels different now. To anyone contemplating whether or not to get these, I'd say – dive in. Your jawline will thank you, and so will your self-esteem. Here's to looking and feeling like royalty! 🤴 Read more

Had decent resistance and it's convenient. Gives a decent workout. It does have a squeek when doing jaw workout due to teeth but I can ignore it. Read more
