Dear Joe, I would like to thank you for your wonderful product. I suffer from Cluster Headaches which are nicknamed suicide headaches because of the severity of the pain. My cluster headaches are chronic and I suffer every day with at least 6 headaches a day which can reach a level 10 pain level on bad days. My whole life is centered around my headaches and your product has helped relieve the pain and many days I spend 8 hours or more using this product. I have spent thousands of dollars on doctors and medicine and the Temple Massager has been more effective than anything. Thanks again for your Temple Massager because it has truly been a godsend. Best wishes.
