Query: Terrible dryer

I bought three of these dryers for my salon in October of 2010. All three of them quit working last week. 2 on one day! I like the rheostat controls and have had this dryer in the past with one that has lasted 3 years. The recent quality must be compromised for the new ones to break so soon. I would not recommend this dryer.
