I agree, very easy to install and I like the all metal construction. I got mine with solar power but without the sensor (I just like the programming part and my coop area is shaded in the summer from a neighbor's large maple tree). It seems pretty weatherproof and there is a You Tube video of someone using a hose to water down the control box and it works flawlessly. Cost is worth it to me also just for the reliability standpoint and I hear they stand by there product.
