C'est pas ouf, je ne sens pas les muscles travailler, par contre le gout est bon, a part sa j'aime pas

I am very pleased with this product, it does everything it needs to do perfectly. It is very flexible, you can easily make it more difficult by drinking some cold water or just adding more gum. The QR code you can scan leads you to a lot of videos with in depth explanations and guides. I received the product on 28/04/2025, the best by label says 02/12/2025. This is excellent, I don't have to rush and can take my time chewing.

I've been buying this since 2024. Only giving 3 stars because 60% of times, this product comes damaged. Sometimes it's so heat damaged to the point where it's softer than regular gum.

Dit is een geweldig product raad her zeker aan om het te kopen

very good
