The RainMachine looks like a great choice, too! I hope that The Iro will be able to surpass the RainMachine. They have a tough hill to climb to compete with RainMachine’s ability to update to NOAA every three hours, exact location data, no rain months, adjusting for daily precipitation, adjusting for daily hi and low temperatures, water saving calculator, cycle and soak and the digital display.
Personally, I went with the Iro and am patiently awaiting the updates. They have been great with keeping their customers informed of changes, delays and updates…thank you for that! Iro’s iphone app in very easy to navigate and has few delays.
