Query: Impeller does not last

Clearly all these positive reviewers have not owned the blower long enough... I've owned two now and each time the plastic impeller breaks after 18 months. Google for cs100 (the predecessor to this product) and read other reviews and you will find very consistent reports of the impeller breaking after 18 months. Even worse, Black&Decker does not sell a replacement part, so you get to buy a new one after 18 months and chuck this in the landfill. What a waste. I suggest you keep looking for another product.
