Product review (5 stars): Absolutely Perfect
I hesitated to buy these, especially at such a low price. How could they work? Well, they DO work! The water resevoir holds over a quart of water, and I'm having to refill it every day. No more waking up with a sore throat or chapped lips! I bought one for the living room and one for the bedroom. They are the BEST investment I've made this winter, so far.
