Steel Avis 

Really good product, gum is good and it was delivered WAY quicker to France than I expected.

Awesome. 2 of these pieces is the equivelent of me chewing 8 pieces of regular gum at once and yet the jawline gum doesnt lose its strength like normal gum.

Over half the pieces are unusable due to leaking gum material from the outer shell.

I recently purchased the Jawliner set. They arrived quickly, and they are high in quality. I feel my jaw muscles working in the right areas. I recommend this if you are looking for something reusable and effective. And Matt provides great customer service!

I am giving one star on this product doesn’t mean I don’t like this. But I didn’t like the way that there was a lack of communication between the company and customers. Also, the package came with two of the gum boxes opened. I am disappointed in the service but not the products. I won’t say it works but it’s a pricy good type of gum.

STEEL Kamejda mastic jawline gum: Is this product inexpensive? No. Is it worth the cost? Yes. When you have gone your whole life with an average jawline and without really knowing how you can exercise those muscles, STEEL gum is just what the Dr ordered. I discovered facial exercises (Carol M.'s) about 18 years ago, and they have served me very well - just do them. There is an exercise for the jaw where you ball your fist, nest your chin inside, and scoop your lower jaw like your mouth is an ice cream scoop. Not a good look! Not very effective, either. This gum wasn't around back then, but I'm glad it is today. There are many similar gums on Amazon from places like Turkey, but I'm hesitant to chew those as there are reviews that they stick to your teeth, etc. This gum absolutely does NOT do that. It is just a perfect aid to building your jaw muscles (slowly but surely). I use in conjunction with a plastic/rubber jaw exerciser. There is a deal where if you buy 3 the price for each then is cheaper than just the single canister. Also, when you put in the order for 3, you are presented with the option to buy a 4th for like half off. That is what I would recommend, because it's not like these canisters last forever. Out of 4 canisters I've gone through about a quarter to a third in a month, so I still have a lot left. Spend the 80 bucks - you'll be glad you did.

Very high quality compared to Amazon brands. My only regret is I didn't buy more.

Nice big pieces, great customer service, much better than any other brand I've tried

I have thoroughly enjoyed this product, although I was unlucky enough to receive a couple of sticky pieces that I read about here(hence the 4 stars).
As soon as I contacted their customer service about the issue, I was instantly refunded the amount. 5 stars for customer service definitely.
Will order again if sticky gums aren’t an issue anymore, and can strongly recommend trying it out.

Really great customer service! Matt checked in some days after ordering the product to make sure I got it. I had some issues with the delivery and Matt helped a lot.

The product itself is also very good! The first couple of seconds the taste is not really pleasant and the texture is a bit weird. However after about a minute of chewing the piece became more gum like (but harder) and the taste became nice (not really minty, but still nice). The taste also lasts much longer than a standard piece of gum!

I have ADD and for me this is also a great solution to stop me from biting on pens/pencils/necklaces. I'm excited to see any improvements in my jaw also :)

First thing, there was a problem with shipping and other stuff, when the product finnaly came it taste like a concrete or plaster, and after first chew of this material i smashed it into 1000 pieces like it was nothing, i dont know if this product was too old or what.

Great product and customer service!

Matt was super helpful, ensuring my package arrived in Canada and checking in with me unprompted to see if I’ve received it.

The gum container is a little tricky to open but that’s really my only constructive feedback. I’ve been chewing for about a week now and swear I’m already starting to see results. Will be ordering again.

Amazing product, already seeing results after a week
Also the delivery was very quick

Had some bad pieces and had the packs replaced easily and right away. Great customer service

Great service, great product. Thanks

I ordered the product but unfortunatly there were some problems with the shipment. I reached out to the support. And i got a fast answer, and they told me they would send a new package. Asked a few questions again very fast answer. Great costumer service! The gum has a funny taste you have to get used to. If you get a soft piece just add another piece. Well deserved 5 stars.
