Rachio 3 smart sprinkler controller (16 zone )

I switched from RainBird (it was such a headache to use it) to Rachio, and I am very happy using this smart controller. Last year, my Rachio gave me a little trouble connecting to wifi. Rachio graciously replace it promptly. But the turnaround took a few days, and I couldn't go days without watering. So, I bought another unit Amazon (God bless the Prime - it came on the same day for me). I didn't want to go through the hassle of switching the controller again, and I just kept the replacement. Since I haven't had any trouble so far, I decided to sell this replacement I received from Rachio. excellent for everyday use. superior materials and excellent craftsmanship ensure long-lasting durability.
