This hurts, can definitely tell it’s working the muscles

I've been using this chewing gum for several months. It's been very good but. I am completely disappointed with the new extra hard gum. Tried out the first gum and noticed something odd, then threw it away, took out the second gum and is just like chewing on glass. shortly i had this metallic flavor on my mouth, Then realized I was bleeding. my gums feel a little bit swollen, and overall the flavor fades away very quickly after chewing. It feels hard,stiff,unchewable, and very uncomfortable to engage with my teeth. I need to feel the mushyness of the gum in order engage a good work out for my masseter.

Terrible product the advertised flavour only lasts for about 10 seconds then you’re left with a non pleasant taste. The gum itself is hard as advertised but when you bite into it initially flakes go everywhere and get stuck to your teeth gums and you need to swallow them or spit them out if possible. The only reason it’s not a 1 star review is because the gum is hard and does its job however I’ve tried cheaper alternatives with longer lasting flavour and without the flaky crunchy pieces. Definitely not worth the premium pricing for the fancy packaging stay away and use cheaper alternatives.

Shame because I just bought the mint flavour from this same brand before and it was fine, but the packet I have just got of this blueberry is either out of date or seriously faulty as it has just turned not into gum but into sharp small flakes and tiny pieces in my mouth. And it doesn’t allow me to get a refund or even replace it with a new pack. Horrible experience !

Very good

The gum shatters in your mouth and is unchewable. The taste is highly chemical.

gum is rock solid the the point you can hardly even chew it

Excellent, good taste!
