Philips HF3321

Been using this for a few weeks in an Ohio winter. Not sure if it is making a difference or not, but it can not hurt.

I use it every morning and afternoon

I\'m up at 4:30am heading off to a very stressful job. Now,each morning I take 20 minutes to drink my coffee and sit in the glow of the LiteBlu. I\'m a new user but I really think it\'s been very helpful. My energy level seems increased.
