The misting system itself is pretty good, but the timers are junk! You need a engineering degree to program them! I emailed them before purchasing and asked what timer would be best for my needs! I ordered the one they suggested and could never get it programmed. It met it’s demise when I ripped it off the wall! $300 down the drain! REPLY: Patience grasshopper ! All 3 timers have different features and are suitable for different applications. Just follow the instructions to set them up or ask someone tech savvy if you get frustrated, not difficult at all. Set time, set programs, set to AUTO.
