"This is a good quality heating pad that does its job pretty well. My one issue, though, is the ridge down the middle. I’m sure it has a purpose but for my application (soothing my temporomandibular joint pain caused by bruxism) it makes it so the spot where I want full coverage of warmth is broken up by the ridge. But still a great product I would recommend to someone seeking a head heating pad."
