ROCKJAW® Hard Jawline Gum - Tuff Gum 2.0 with B Vitamins (Stim-Free) - 10 Pack - 100% Xylitol, Aspartame-Free, Sugar-Free (Strawberry Smash)

I love this gum ! Not only does it do ( and u feel it ) wonders for ur jaw line . I actually like the taste of all of them iv tried so far bubble gum , strawberry ..tropical my least favourite is mint . The flavour lasts quite long and I actually find it quite a grounding exercise to keep me present . It’s tough but u get use to it . I buy this brand now quite regularly. Great product !

What makes this tuff to chew is the lack of flavour. No taste after no joke 5 seconds. Apart from that does what it’s supposed to do

Not so good To hard Not too much taste

Does what it says on the box, it’s a workout for your jaw! Very strong, could even hurt if your jaw isn’t strong enough.. my partner tried one and said it hurt but I can handle it. Only downside is the flavour is gone after about 10 seconds, but apart from that, very solid product!

I bought this as I thought it would last ! I couldn’t even crack it never mind chew it ! I threw the towel in after 15 mind

Ordered it for workplace anxiety relief. -Hard texture first however minute later falls apart. Not really tough. - Loses flavour in a minute. - Not worth the price. Also I would like to add: If you are insecure about having a weak jawline, loose weight it will became much better. Even if it isnt, having a 6 pack beats any jawline..

Will these build stronger, bigger jaw muscles? More so than regular chewing gum certainly. I like to chew gum when I am driving and standard gum won't last a couple hours behind the wheel, these do so they've done their job. The taste disappears quickly and they seem like they are going to disintegrate in your mouth at first but persist and they will form into a chewy gum which is significantly firmer than standard gum. They are expensive for what they are but for occasional use the price can be justified.

Bought to 'chisel' my jaws and strengthen them. Good flavour, however, it did weaken quickly but continued as a more subtle flavour afterwards that keeps for a long time. Very tough so be careful if you have sensitive or brittle teeth. Will definitely buy again. This flavour is more of my taste than the mint one and I think is more pleasant, however, one should but true to their tastes.

Extremely hard tasteless non sweet gum . It’s awful and wouldn’t you know it then refusing to let me return it ,biggest waste of almost $6 bucks I’ve ever spent.
