Product review (1 stars): No Product Support
I installed this unit in July 2014.  It looked and worked great.  The vent function was really good.  In January 2015, one of the lights quit working.  I replaced the bulb with the same type and it worked for about four days.  Then both lights quit working.  I replaced both bulbs but the lights would not illuminate.  I have tried to find a replacement transformer, but no repair shops in my town have heard of this unit.  I can't find anything on the internet and the manufacturer does not answer the phone and Amazon doesn't appear interested.  Folks, if the manufacturer doesn't support their product and is indifferent to their customers, you should avoid this company at all costs.  American products cost more, no doubt they are made in China like this one, but at least you can get parts.
