Q: Hard to find a better direct-wire wall timer of this quality. HOWEVER, this is the third one I have purchased so be warned that they will eventual ware out. The timer will eventual stop counting down and get stuck, leaving your device always on. I have mine hooked to turn off a wall heater in the bathroom. It works well for that. NOTE: Even though it will eventual ware out, they usually last a few years before they do. So yes, they are worth the price. BE WARNED: If the start waring out replace immediately as they will get stuck in the ON position... Thus, 4 stars.
A:
Positive
