I'm sure that many will think this is the device they're looking for; it was created for a very specific need. However, mine went completely dead "no0p" within approximately three months. I had it installed by a professional, licensed electrician, so I know it was installed properly.Intermatic timers, a name renowned for automatic electric timers needs to go back to the drawing board on this one's design. Of special concern to me is that many folks purchase this item to enhance the security of their home, and with this product's miserable track record on reliability, it could be putting people's home and property at risk.Intermatic seems to be willing to replace this item free of charge, however, I would recommend purchasing another brand of digital timer altogether until this model's problems are resolved.
