The main reason I bought this RainPoint water timer is because it was the best I can find that is WiFi and has an app. I am very pleased on how it has been working. You don't have to be a tech to connect the unit to your WiFi. And the instructions was easy enough to setup the app. I needed the app because I travel alot and I needed access to control the unit from anywhere. So far, everything I need to do, I am able to do it remotely. Plus, the unit is in an area that is not easy to get to. So being able to remotely turn the system on or off has been great. Or even changing the water schedules for each of the 2 zones. So convenient.It is well built. Very sturdy. I can tell that this unit will last. And the design on the unit is simple with simple buttons on it.The app is Easy to Use. You can connect multiple units to it. What is very nice is that I can set multiple plans / schedules for each zone. Once setup, I can easily turn on or off a plan for each zone. Or I can have them all on at the same time. So you can set a zone to start at 5am for a certain lend of time on certain days. And you can also have that same zone turn on at 9pm on certain days for that same zone. Also, if it has been raining, you can easily turn on a rain delay for 24, 48 or 72 hours. Amazing!There's more. I can manually turn on the system and set a timer. So I can turn on zone 1 manually and set it to turn off automatically after 15 minutes. I use this feature alot when I am fixing or checking our my drip system. The app also tell you how much water has been used the last time you turned it on.There are so many other features that I have not used yet. I am very Happy I bought this unit and I Highly Recommend it.
