I received this device there some days, and have been used every night. I suffered for more than a year of very strong pain in one foot: after a massage session by this unit, the pain had diminished considerably; After two sessions, she disappeared. Miracle !!! :-) Since, I continue to use it daily for the pleasure of deep relaxation it provides. It's very nice, especially with the heat way (but this latter point, it is also a matter of taste) My only regret not having bought earlier! One final note: many reviews on this site indicate that this massager is enough (or too) noisy ... But I found particularly quiet mine. Would it be a new version?
