I bought this product a month ago to replace a 20 year old model.  My DLE3600V is like a Cadillac compared to my older model.  The lint detection feature in the exhaust duct may have prevented a house fire from occurring by letting me know service was required.  Only suggestion I have for product is to add back-lighting to controls.  In low lighting, you need a flashlight to illuminate the control surface to see your settings.  Apart from this, great product!
