Steel Omdömen 

I still haven’t even received it 11 days after ordering. The tracking is all over the map… literally. You can’t do that in the Amazon era and expect to have a successful business….

Excellent product and excellent service. How long will one pack of mastic gum last before I have to purchase another pack? Thanks

The product is good and effective. Just please be careful with the softer pieces and take them out of your mouth immediately before it sticks to your teeth ;)

I think the reviews on website are not real. There are way cheaper options.

This whole thing is a big lie, a scam.
The YouTube channel "Matt Phelps", the entire website "steeljawlinegum.com"; everything he tells us about his own experience and so called customer reviews. The before and after pics are probably faked, this is why they were removed from reddit.

The proof was not even hard to find. Matt Phelps himselfs boasts how much money he made out of the dumb people buying "his" product.
If I may quote: "I don't care about smart. I want to be rich. [...] All this is just a rationalisation for my lame product: Steel Jawline Gum. Lame, but people love it, and pay for it. I was embarrassed to sell it in the beginning."

He will delete it, but you can contact me for screenshots, in case you are interested.

There is nothing more to say, I guess.

And to you, Matt: You may have earned some money through your stupid product and many people believed you, congrats. And for sure, this is how capitalism works, but shamelessly lying to people for some bucks.. Just remember that everything comes back to you.

Best wishes to Bromma from Germany :)

Edit: I do not recommend any other products and I am surely not your competitor. If it was a fake profile, why was it deleted the same second I wrote my review? And you call me a scam, I‘m at a loss really.

No issues, the packaging is a bit weird but that’s abt it

I never received it...but Matt responded very promptly and I am using the product daily. It's a little pricey but worth it. I am changing my review as it was USPS that was the problem, and the way it was handled by Matt is more than I could ask for.
Thank you Matt.

Please send again along with the tracking number for UPS. Thank you.

I’ve bought mastic gum several times, and this is the best quality of all the ones I’ve tried. Clearly effort was taken to find the right supplier. Good packaging, marketing, customer service. My shipment arrived quickly. Keep up the good work with your business endeavors Matt!

Best mastic gun in the game. I've tried several types of this stuff, Steel stands above and beyond - big, hard pieces of high-quality mastic gum in each can, and cans don't vary much - every one I've received so far has been great. Plus... the stuff works! It gives you jaw a serious workout and one piece lasts a long time. A++ gum for jaw strengthening.

Bought the combo pack of 3, enough to last me at least a few months of good use. Just an FYI if it's your first time trying mastic gum like me, the taste will be a bit of a shock. I couldn't have it in my mouth for more than 20 minutes, but the second use I was prepared for it and it became more than tolerable, and I'm a guy that's not easily sold on an unflavorful taste. Now I can chew away all day no problem. It has an earthy taste, very vaguely like pine, but it's subtle and actually quite nice. [That's a comment about mastic gum in general, not this branding specifically]

Rinse each piece under cool water before using to remove salty taste, let it rest in your mouth for a minute or two to soften it up. Chomping on it immediately will break it into crystallized pieces all over your mouth. Just a few tips.

Overall I love the packaging and the case that stores the gum. There's a little separate storage pocket at the top of the case where you can conveniently store your used gum for further use so you don't have to throw them out after. Really nice!

Overall I'm extremely happy. I could have paid a *tad* less buying mastic from somewhere else probably, but I had to support the man who provided me with the information and resources I needed to develop my facial structure. Thanks again

Awesome costumer service, fast response time and they actually help you out and answer your questions.

The costumer service is the best. Quick and straight to the point. Thank you.

Best gum for this purpose I've had to date. This stuff is top-notch mastic gum and it really does work to help strengthen your jaw if you chew it consistently. Some people like super-flavored gum and such, I actually like it's very basic (borderline tasteless) flavor. It's very easy to pop it in and chew for awhile at, well, really any time. Stock up!

The taste takes a bit getting used to. But I like it.

I’m having an easier time with tmd since I started chewing mastic, even breathing as improved tremendously. I recommend this stuff to anybody looking to strengthen their mandible.

The gum gets so sticky and it's not "strong" at all

In a nutshell: product is exactly as promised, plus the customer service is as great as it gets. Matt answers every question and even left a handwritten note with my order. Small gesture, but it shows that he genuinely cares.

Have seen great results - and im healthier than ever because of this product!

This is some kind of scam. The gum isn’t gum. More like super glue. I can’t get it off my teeth or my fingers and it seems this must be a scam or some scheme. I really need my money back this wasn’t cheap and now I have to spend the day picking this glue out of my teeth !
