I ran into some installation issues and made the mistake of trying to call their 800 "support" number.  After many repetitions of "go to our website" I finally got into the cue but after 27 wasted cell phone minutes i hung up.  I tried the FAQ section of their web site and also found not help; I eventually got things figured out using Google!  Anyway, the timer is very easy to use, setup is quick and intuitive, and everything worked right out of the box.  I strongly recommend this timer, just don't count on any help from the manufacturer.
