I use it every day for a few minutes during my evening routine and the results came after about two months. With more frequent use, I imagine that the results will come sooner. After 4 months they prokously, which was resolved after a short consultation with the customer service center by sending new ones, communication fast and helpful.
The big problem I experienced initially was the placement of the boosters in the back of the stools, which made me gag unpleasantly and I almost stopped using them because of this as a person with a sensitive gag reflex. BUT! I persevered, got used to it and on the contrary I have the feeling that it has strengthened my difficulties with this reflex, even at the dentist I have fewer problems thanks to it.
I recommend it.
After regular use they really work
Customer support
Non-toxic materials
After a while, they will break (but can be quickly resolved with support)
Not suitable for people with a sensitive gag reflex (or vice versa, see note)

I've already thrown out a few cheap products. This one holds up and working out with it is really hearty.
The booster is quite expensive, but it works.
Quality of execution.

I am trying to increase the size of the jaw muscles, using similar principles as in strengthening other muscle parts, i.e. overloading during exercise and then resting for about 3-4 days for recovery, of course combined with proper diet. I have seen a slight improvement in a relatively short period of time, so it meets my expectations. However, long-termism is necessary. Of course, after the exercise itself, the muscles of the jaws are briefly considerably pumped with blood and really noticeably enlarged, which of course helps muscle growth in conjunction with a proper diet. I can definitely recommend the jaw booster for this purpose.
great for strengthening jaw muscles
great for getting rid of fat in the face area ( but necessary in conjunction with diet)
beautiful quality packaging
great communication and support www.jawinner.com

After a couple of weeks you can really see the difference on the jaw. I bought it first as a joke, naively thinking something would change. However, if you give it time and regularity, you will really see a difference. Definitely better to pay extra and not buy the cheaper versions ( my own experience ) (:

Hardness selection
You can take it anywhere. It looks like you're just chewing gum

Not recommended for people with a strong gag reflex. I only have to chew one cube with my front teeth, the other one is in my supply: ))
