I've had this dryer for approximately 10 years which is sited on an outside wall. In that time it has been completely problem free. I'm so glad I bought it as my normal washing area is located by traversing a stairway which, as I get older, causes it's own problems. It's just so much easier to pop along to the end of my building on the same level. I easily get two was loads on it and even after all this time have not had to replace or tighten the line.
