Comes in a very sleek package, looks nice and professional. I use the exerciser in the car, and can leave them inside the case that was provided. Great workout, it makes me feel awake. The resistance is sufficient, and it feels like a very durable product.

Love the product. If you use it twice per day every day consistently - you will see the results fast but as the instructions say do not overwork your jaw muscles. I use the minty one for 20 minutes in the morning and lemony one for 15 minutes in the evening and it BURNS!!!! I feel the exercise for sure.
Wayne S.
Didn't think it would work as well as it does.
Stephen R.

The delivery was very fast and when I opened my package I was amazed. It is a very high quality product. Packaging is super nice and pretty. You also get clear instructions inside the box on how to use the product. I started with the mint one and switched to lemon in 1 week. Flavors are quite nice and natural. Also I love the fact that it has carry cases for all 3 exercisers and lanyards which makes the whole experience even more comfortable.

Flavors are so awesome, I have never seen any other company that has flavored jawliners and they actually work!!! I can feel blood flow into my jaw after 2-3 minutes of exercising and it is quite a workout and I can see the difference already. Highly recommend

Very satisfied with this jaw exerciser. This is the only brand name that actually makes flavored ones and the flavors are awesome! Very durable and the size is perfect. Does not trigger gag reflex...Love it!

Wow everything about this product is amazing. I purchased the Rockville Jaw Exerciser for my TMJ issues because everything I've tried before wasn't really doing the trick. Firstly the package came early which was a wonderful surprise! The packaging itself is classy, each component having its on compartment and box to keep the strengtheners in. The card has clear instructions of how to use and clean the strengtheners. I started noticing results after 5th day already, my jaw doesn't click anymore which makes my headaches and anxiety almost completely go away (please consult doctor if considering using for medical purposes). These people definitely know what they are doing and are so confident in their brand that if you add them on Instagram and let them know your purchase they'll even send you a free gift! This is an awesome company that I would recommend to anyone looking to lift their face, strengthen their jaw, or even just relieve stress. Thank you Rockville, will definitely be buying from you guys again!

I like the product bundle. Flavoring taste great. Lemon is my favorite so far
Debra L.
Ok, I was skeptical, but you can feel this one working.
I'm only on the beginner jaw shaper and it feels amazing. Don't do too many in the beginning. I did and was a little sore. I'm an overachiever. LOL
I love that this is a small item that I can have hanging on my neck around the house. Easy to remember.
No batteries. No fancy set up. No excuses. Super simple.
I'm really excited about this jaw shaper and can't wait to get to the next level. This one is really giving my jaw a workout.
I hope this helps you.
