It can be harmful for the mandibular joint
By Kindle Customer on Reviewed in the United States on August 22, 2025
I bought this product and I use them a couple of weeks maybe twice or three per week and I develop strong pains and rigidity in my mandibulars joints, something get very wrong. I don't use this anymore. I am a couple of month after this and still the things didn't reverse. Sorry but I don't recomand them.
