Title: Great Idea Unreliably Executed
Review: These timers are a terrific idea but, as others have pointed out, seem to be notoriously unreliable. I have had two of them display the dreaded "no op" which no amount of resetting and battery changing has cured. One reviewer has criticized the device for working on a battery rather than line power. I believe this was done because most light switch boxes don't have the second (white) wire needed for a 120 volt connection but have only the black "switch leg". This makes the timer easy to install--just replace the regular switch. Too bad Intermatic is damaging their reputation with this dog of a device.
