I've been using this thing for a couple of months, and it does improve my rest. But I don't understand what is a "therapy hour." If I use it for 8 hours the counter shows 6-6.5 hrs. If all I had to worry about was results I wouldn't care, but for my insurance co. to pay for this thing ($980!) I have to get 4 hrs of therapy 21 out of 30 days. I can't get it above 20/30. It said 20/30 two weeks ago, and it has recorded 4+ hrs every night for the past week, and it still says 20/30. Does anyone know how these things count hours? If I don't get it up to 21/30 before Feb 12 I have to pay for it out of pocket.
