JawzrsizeJaw, Face, and Neck Exerciser - Define Your Jawline, Slim and Tone Your Face, Look Younger and Healthier - Helps Reduce Stress and Cravings - Facial Exerciser (Level 4 - Elite) (Green)

I wanted to wait to write a review, so here it goes.I already have a very noticable jaw line, and this just enhances it. I use it 4 days out of a week and the first day I already noticed results. I bought the 50 pound resistance, it resonated with me to purchase that. All in all, it's about technique. I see people complain about their teeth hurting but to me and my opinion, you are likely angling it wrong. I would work in front of a mirror and see where the muscles are staining, to understand how to better bite the thing. Other complaints I saw were that the mouth piece adapters, and how people needed a new one after a few weeks. I boil it with the device and the pieces go back to new. Overall, great product. I feel my jaw getting swole, women have noticed and like to trace my jawline. This product is genius.

Was skeptical at first, but the logic is there. Its weight lifting for your face. I used all three levels over the course of about two months and saw big differences in my jawline and chin. The trick I learned here is to use it daily, before bed would be best because it allows your face to rest. You must be willing to absolutely tire out your face muscles or the improvements won't appear. It gets easier after a while so I would recommend doing more and more reps/sets (about 500 bites a day) (50-80 bites per set). *TIP: chew a lot of gum*Would also recommend beginning on level 2, because level 1 becomes too easy after a couple of days.Lastly, it will tone your overall face but you must also be lean in order to give the jawline a more defined looked. Overall great product!

Works as advertised, I can see the results but the device doesn’t last. Just ordered my 4th one today. After about 6 months the rubber cracks along a seam so it loses tension and I have to order again. I’m using the dark green 50 lb version. Otherwise it’s a great product.

I decided to try this out just to see if it would actually do anything. It’s a small tool you put in your mouth and bite down on to work out your jaw and neck area. This one is one of the higher resistance levels, so it takes a bit of effort, especially at first.It came with a little case and some extra bite strips, which was a nice touch. It’s pretty easy to figure out how to use—just bite and release over and over. I started doing it for a few minutes a day while watching TV. After a while, I could feel it working my jaw muscles, which is kind of the point.One thing I noticed is it takes some time to get used to. At first, my jaw felt a little sore, and the rubber has kind of a weird feel until you break it in. Also, it’s not something you want to use around other people—it looks a little odd and makes your mouth look pretty full when you're using it.Overall, it’s a different kind of exercise tool. Not life-changing, but if you're curious about working on your jawline or just want to try something new, this does what it says. Just know it takes a bit of patience and consistency to see results.

The bite strips came off on the first time using the product, I would not buy again. I do however have a pop and go model that I have used for a few years, it works great.

It works, but the pressure hurt my teeth. I should have started with purple instead of green. Money well spent.UPDATE:I started using this 3 days ago and the bottom tooth mold is already worn down. Now it’s cutting into my gums.This is disappointing because of the guard lasts 3 days, I’d need 10 of them to get through one month of training. Which would actually be fine, but it seems that the molds aren’t sold separately.SECOND UPDATE:Okay so apparently the company offers replacement “bite strips” on their website, not Amazon. Each pair is $3.00, so a month’s supply would be $30 total.If anyone from Jawzrsize is reading this, you should really consider offering the bite strips on Amazon in bulk packs for the people who want to keep using your product.

Looks funny while biting. Like sucking on a pasifier. Still, I like it. Pretty easy to use. Every now and then the mouth pieces become dislodged, but really no big deal. Going into my second week. I can see a slight difference in my jaw. I got this mainly to try and get rid of my puffy cheeks. I can see a slight difference there too. I notice how my jaw has gotten stronger. When I first started I could do about 30 bites before I needed a rest. Now I can do 50 or even 60 before a rest. I’m going to keep at it. We Will see what happens with two more weeks 300 bites a day.

Got this product over a week ago, using it daily. I saw all the hype surrounding this product and thought "hey why not give it a try" knowing it's probably bs. First things first, the creator of this product was a fighter who had a glass jaw, so what does he know about "strengthening the jaw". Second, Spot reduction is a myth, you can not tone a single part of your body by itself. If you want to have a better looking jaw line, you need lower your body fat percentage or have amazing genes. Once I got the green piece of rubber, on the back of the package it said, "only use the green jawzrsize after one month of using the blue or purple jawzrsize" which basically means, "BUY OUR OTHER COLORS FIRST BECAUSE WE WANT YOUR MONEY". My teeth are starting to hurt after using it. After further research, this product could cause premature tooth loss. Giving this product 2 stars because this company still got me to buy it, even when I knew it was bs. Long story short, if you want a better jawline, chew on some salad instead of jawzsize and reduce your overall body fat.
