Product review (1 stars): Noise, noise, noise, regrets.
I was too dazzled by the five stars and looked over an important review!  First ten minutes it looked nice and then it started making its "clicking noise" for about one minute. It  repeats every ten to fifteen minutes and drove us crazy.  I was sure that the fan should be broken but then the instruction says "the clicking noise" is normal, which means the manufacture is well aware of the annoying symptom.  I just dump it back in the box and am looking forward to seeing UPS pick up truck.
