I'm liking the light. I find I wake up feeling more awake, I used to always feel sleepy in morning and often snooze an extra hour or three if I didn't have anything in particular scheduled.
I'm trying to find the right place to put the light. I had it on my night stand which was great if I happened to be facing that direction in the morning, but I roll around a lot. If I'm facing the other way I don't get much light. Also, when it's there my wife doesn't really receive the light. I put it on the dresser at the end of the bed last night which light up the room pretty well, but my body mostly blocks the light from my face, and the light is also angled slightly upward since it's intended to be on a nightstand.
I really like waking up to the bird sounds, so much nicer than alarm clock shock.
