Steel Avis 

First purchase never arrived and they offered to resend another package very helpful support , cares about giving customers a great experience

So far it is better than a gum. A lot harder to chew on.

I wanted to order the Steel jawline gum and I could buy it from France and it arrived. The customer service is genuinely one of the best. Matt always answered my questions.The gum is hard and I feel my jaw muscles work!

The product itself is awesome and Matt is always happy to answer my dumb questions via mail. Definitely will order again.

Customer service is great. My gum was thought to be lost. They promptly refunded my order.

The gun ended up coming in, and I let them know they can bill me. They told me not to worry about the charge because of the shipping issue. The gum is great as well.

I see and feel a big difference and so does the family but it seems i have to chew for hours on 2-3 pieces to exhaust the muscle. An excellent product but it seems all the hypertrophy possible has happened a few weeks in (i chewed on that turkish stuff before). For my assymetry it helped quite a bit in conjunction with proper tongue posture thpugh it wasnt the be all end all i was perhaps naively hoping for. 10/10 for what it is-tree sap. Thanks Matt for being one of the only sellers with free shipping worldwide, you saved me $50 in shipping. Cheers

Love this gum! Its actually good for you unlike any other gums and already have noticed an improvement. Chew on people!

Some pieces just stick to your teeth. If some of it does work it’s just a rubber tasting product. Similar to chewing on a condom. When it works it does do the job of exercising the jaw. For the price ($25) I was hoping for a better product not randomly sized crushed raw gum product. I’d just chew 5 sticks of gum instead or look for a better product.

I haven't been able to test the product itself as of now, due to some shipping issues. But the customer support so far has been nothing but exceptional. Fast response rate, very understanding and always motivated to find a quick solution to the issue.

Can't wait to be equally if not even more blown away by the product itself !

Keep up the good work.

Would buy again

Really good product and service. Thanks Matt !

Great product. Works as advertised.

I have noticeably gotten more handsome/attractive (what I was told by female friends) by chewing every other day for two to three hours (sometimes more).

The gum would even last more more than 1 day, I prefer to use a fresh one after every workout though.

Fantastic and welcoming customer service. I can tell Matt Phelps cares about his product! I received the parcel within a day or two, and am over the moon with how much I'd like to recommend Steel Jawline Gum by Matt Phelps. =)

Nice packaging and container that fits in your pocket. Solid workout for the haw

Harder than i thought and made my jaw ache- as promised.
