Query: Didn't even last 2 years!! Heat went out!

I bought this product in Feb. 2009 and I used it to blow dry my hair every day like normal. I loved this blow dryer until it went out on me! All of the sudden one day in Dec. 2010 it just stopped putting out heat and now it just blows cold air! For how much this blow dryer cost, I would expect it to last longer...It didn't even last 2 years!
