What can I say...I bought this for my bathroom which is lacking a ventilation fan and has tremendous moisture issues. I left the unit on 24/7 and it worked very well, with the water basin needing to be emptied every 2-3 days. Unfortunately, after 10 months, the unit started just making a buzzing sound and the fan wouldn't work. I tried to open it up and replace the fan, but it turns out the circuit board is cooked. Since I opened up the unit, I voided the warranty and the company won't honor it. What can I say...$50 is a lot of money for 10 months of use.
