I installed the Rachio when the original Hunter died. Installation and setup was about 90 minutes or so; ideally you will measure the inches per hour for each zone and that will take a bit of time. One of the other benefits is that you can turn individual zones on and off with your smart phone, which makes adjusting sprinkler heads convenient. When you travel, you should leave your wireless router on because the controller will not function correctly without a Wi-Fi connection. Mine is located in the low voltage panel in my garage and has no problem picking up the Wi-Fi signal from across the house.

My irrigation water usage costs about $7 per month. So, I think a high tech watering controller is overkill.
