Query: Buyer Beware!

DON'T WASTE YOUR MONEY: This is the first review I've ever written for a product, but I felt compelled (or maybe "impelled") in this case. Like everyone else who has ever owned this product for more than one season, it worked okay for the first year. Then in season two, the impeller started vibrating during use, and eventually burst into dozens of pieces. The most annoying part of this is that you cannot replace just the impeller, even though it would be very easy to do. So you have to spend $50 to buy the entire blower assy (everything but the battery charger and tube), all to repair a $75 blower, which has the same inherent defect. No thanks. I cannot believe that Black & Decker has not stopped selling this product and not offered a free replacement blower assy to all who have bought one. Last Black & Decker product I will buy.
