Review title: Quit Working
Product review: I've only used this lite a handful of times, when I needed it. I've had it for about 2-1/2 years and when I went to use it the other day I found out it only works when it's plugged in. The display shows that the battery was charging, and then it was fully charged, but nothing I do seems to be able to get it to work on battery power. If I have it plugged in, it works fine. But this defeats the "portability" which is the reason why I chose it over other models.I do think it helps me with SAD, although it's hard to tell if this is due to a placebo effect. I only regret the purchase because it stopped working on batteries. Very disappointing to say the least.
