I set it up, tested it, tried it with a hose and then packed it up and sent it back. If this is what you get for $60, then I need to pay more for something of better quality. It did seem to work and I imagine I could have made adjustments to make it work more precisely. But it leaked. That's because it does not even have a standard hose fitting -- a screw-on sleeve with a gasket. To attach a hose onto the device, you have to turn the device around and around clockwise. And without a gasket, water constantly leaks around the fitting, as you would think it might. I believe it also leaked a little around the sprinkler head. No gasket there, either.

In the instruction booklet, it says it works by detecting the difference between the heat of an animal and the background and then reacts off the motion sensor. I don't know but that seems like a dubious technology for Texas heat, where the background is going to be about animal temperature or higher from June to October.
