Upgraded Jaw Exerciser for Men & Women - 3 Levels Jawline Exerciser for Beginner, Intermediate & Advance Users - Jaw Toner for Men & Women, Jawstyle and Jaw Trainer (3 Levels - Improved Durability)

These were great for my wife and I. We committed to sharpening our jaw line and with the 3 different levels we were both able to use the one that worked the best

J'apprécie que ce produit soit livré en trio, en cas de perte d'une paire. Sa taille compacte me permet de le transporter facilement partout, et dès que j'ai quelques minutes libres, je peux l'utiliser. De plus, j'ai constaté des résultats après seulement une semaine d'utilisation, ce qui m'a agréablement surpris.

They say to beware of counterfeits and then send it in generic packaging from China (see pic) with no box or branding of any kind and no individual cases for each resistance as advertised. Doesn’t even say which resistance is which and comes with no instructions. You have to check back on the ad to see which is which. If you can get past all that it seems to work at least.

Yes, we have jaw muscles and these will grow them!I have been using these guys on my commute to work 40ish minutes, and have seen results. Now I wouldn't say it will give you a chiseled jaw, but there is definitely greater mass.My concern!: I feel soreness when using the product, and like any other exercise I imagine the "form" of the movement matters, I have come to realize you are able to chew in different directions and became weary after I felt a discomfort from my jaw joint. I would recommend being weary of placement of both silicone pieces and feel for symmetry.

Got it for my son. He is happy with the product
