NO STARThis is a dreadful company regarding customer service. All women CSA are in a terrible hurry, they will not listen, they will speak over you and if you complain, they buzz you out or hang up on you.It may be the way to do business in China but it is frankly shocking when coming from Fort Lauderdale.Product (fan) is OK but DO NOT need spares or it will take you months of aggravation.
