I have not dislikes for these timers. They are compact and with the pigtail power cord you can plug it in and program it without having to bend over so far to see it when programing. It should prove weatherproof for a long time it you give it some protection from direct contact with rain or snow. I would be worried about it being ruined if left out on the ground or connected to an extension cord where the elements could get to it.It is pretty simple to program if you follow the directions.
