- It does the job - keeping jaw closed comfortably, without smashing my ears
Just O.K. - It does the job - keeping jaw closed comfortably, without smashing my ears.  However, it has a lingering odor (petroleum-like), which will not wash away, and didn't dissipate after a week.  In fact, it lingers in my hair in the morning.  This is disconcerting, as I do not wish to be absorbing something harmful.
