It was easy to setup and has worked fine ever since. It caught one actual leak and always works correctly when I test it. Good product in my estimation. I still check the system every couple of weeks with soapy water and pressure gauge and I always shut off at the tank when not using. The electronics augment my safety procedures, not replace them.
