as described hurt a bit to use [SEP] this is exactly as pictured and describes and seems to be a good product but it hurt to use it it does not mimic natural chewing motion and if you have any preexisting jaw issues it can exacerbate them if you have a healthy jaw then i imagine this would not hurt but this triggered clinching and strain and made my jaw hurt a bit i think it is meant for those who have zero stress and no tendency to ever clinch their jaw good luck in your search
