I had been eyeballing these and other timers for quite a while before finally going with these ones. One of the main reasons for choosing these was the ability to integrate with my Home Assistant which worked pretty well in my first summer of usage.The setup of these controllers was very intuitive however I did get a bit confused when it came to zones and schedules. The app seems to be designed for an irrigation system not 4 individual "systems" so switching between devices is cumbersome and took some trial and error. I was able to overcome this annoyance eventually by integrating the system with Home Assistant where I set up a dashboard to control them at the push of a button and turn schedules on and off all on one screen. This really took these from nice to awesome.For my setup I have 2 faucets one on either side of the house. I used different splitters that allowed for more water flow as the included manifold seemed to restrict flow too much. On each side I have 2 controllers with the wifi/bluetooth bridge inside the house between the two faucets . This allowed me to control all 4 very well.With these I was able to setup 4 sprinklers the night before and schedule 1 on each faucet to run their 2 hour schedule and then the other 2 would run their schedule giving me 4 hours of watering before I left for work. I was also able to move the first two and schedule a second 2 hour window so in one morning I could hit 6 zones with 2 hours of watering. This was WAY BETTER than previously watering at night for hours and then waking up sometimes at 4am to turn on sprinklers in the morning and sometimes forgetting and letting them run too long.Overall I'd say the hardware is great but the app needs work for these devices to be more user friendly.
