Received the dual controller replacement with ease and promptly. Just set up and attacjed. so too soon to see if andy problems. Orbit has been awesome about taking care of clients not only with questions on operation, but also product failure. There seems to be a good number of issues with the product, but in research found their other main competitor also has the same types and numbers of problems. I have Orbits at the present ( 5 year history) and plan to purchase one more now.
