I started last Saturday with the Lite Book- $199 for 30 minutes. Crossing fingers that it helps if the depression has any seasonal aspect.
My first day was a rainy gloomy morning and I felt more tired while I was using it. To bad it does not work if your eyes are closed.

My Pdoc said if I do not feel any benefit after 3 weeks get my money back.
