I've never had a problem but I always use the simplest, cheapest Orbit one that you can get on Amazon or Lowes. I do agree, that Hunter one that came with the hose is a problem.

Simply throw out the Hunter controller and install a DIY Rachio controller. It doesn't use a rain gauge, it listens to the weather radios plus has seasonal adjustments, etc
