Review: Intermatic is a brand you can trust to last! - We're in the lightning capital of the country so we often get calls from clients whose digital timers are fried. We recommend these mechanical timers and they last and last. Easy to install and super simple for the clients to adjust their times by themselves. We never go wrong with Intermatic Timers.
Review: Right Part for my Setup and Works Great - Perfect replacement. I did the research and bought the correct part. Installation was easy. I did have to extend a wire to reach the other timer and to reach the breaker. Working great so far.
