Noisy and worthless
I use a massager on my jaw line for TMJ almost daily.  The frequent massage has all but eliminated the headaches and need for medication, but this massager is no good for me.  It's very noisy and rattles a lot.  It seems to try really hard, but it just makes a racket rather than anything productive.  Not worth a dime, much less this pricetag.
