Negative Positive
Title: Same problem as everyone else.
Review: I got lucky with my first unit - it lasted almost a year. When it failed to work and only gave the No Op display, I figured it was a voltage spike or something and replaced it.The second unit lasted about 3 weeks. I returned it to the store I bought it from and tried a third unit. That one lasted about a month.I've since replaced it with a motion sensor switch, which has worked perfectly for over two years.
