I have noticed that the only reliable effect that my Sota MPG5 magpulser produces in me is tired sleepiness.
For two years I have tried it on teeth, joints, sprains, ect, but honestly it has never noticeably improved anything except perhaps the heat from the coil having a warming effect.
It does seem to put me to sleep, so much so I use it as a go to sleep aid. It works great behind my neck or on my spine.
