It was easy to install, set up and program. I watched it for a few days to make sure it worked but it is very reliable and accurate, I don't have to go out to open and close the access doors anymore. I think it is great and only wish I had got it years ago!
I have it set up on a test panel board until spring because I won't have any chickens until then.
But it works great under multiple practice operations, over and over, to test it.
It turns out to be a very good way to see it in operation before it is installed.
