Jawzrsize Jaw, 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)

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.

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.

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.

Nice product. After reading the reviews, I initially did not want to product but I opted to buy 1 week later for my own experience. I have seen reviews where people state it hurts their jaw or teeth but that is not due to the product. That is due to not following the recommendations for exercise (3-4 sets of 15-30 reps and taking a rest day if sore). Too many reps can result in soreness like any other workout. If your teeth hurt after using, that is most likely a dental issue as the product is certainly softer than candy.I use it daily as I try to get in 50 reps per set and I can feel my jaw getting harder and thicker. Unfortunately, the bite strips are worn down within 5-6 days so it is highly recommended to purchase extras which is not sold on Amazon (-1 point). In addition, the SAME product comes with a carrying case which is not included with the Amazon purchase (for the same price: -1 point). These are essential items required for using the product that are missing if purchased from Amazon.

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.

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!

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.

First thoughts of the product after opening the packaging was that the items were cheaply made. This boast being one of the higher end products but does not match up to cheaper priced ones. There was a distinct rubber smell and taste to my Jawszrsize. The included case does not close and the rubber cord is weak and grips to hair allowing for tangles and snags. The inserts that your teeth rest on are a hard plastic that is uncomfortable and protrude well past the rubber body making it hard to fit your jaw around/over. The product is also pointless if you are a active user of food. If the jaw muscles are over stimulated the user might feel discomfort such as: popping (like when you over chew with gum), and cramping (let it be known the jaw muscles are already very strong and when they cramp it can hurt a lot). After using the product quite a bit it feels like I just bought into someones get rich quick schemes.
