Query: Gone Through Two, Both Stopped Working

My first of these switches lasted about a year, and was replaced by Intermatic. The second one lasted for a few months before getting the popular "noop" condition. Save your money and stay away.I replaced mine a few months ago with a Leviton LCD Timer from SmartHome. (Unfortunately it's not sold on Amazon) The interface is simplistic, and you only get one daily program. But it WORKS!
