nice product but installation is more complicated than it appears in terms of figuring out correct wiring and fitting it in existing electrical box
JOERG -- martinez, CA   7/9/2012
Finally a 12-hour timer! Design matches other timers from the same manufacturer. I use it in the laundry room to keep the fan running during washing and drying cycles. No need to go back to the laundry room later just to turn off the fan.
