Great 1st visit with Dr F. Very patient and understanding. Sleep study was PAINLESS! Great technician. Online for less than a week. I can read my daily results online with the CPAP I was prescribed. Good Tech that came to my home to set up the CPAP. Chin Strap was not sufficient. They ordered a different "Halo". It arrived yesterday. 1st night was very good. Good suggestion for my condition. Just waiting for Dr. F. to schedule a follow-up visit. GG
