On this type of stuff, there's not a lot to review; the question is whether it works. It does. It would have been 5 stars if it had come with instructions or a better wiring diagram. I know that there are several applications (mine is powering a zone control panel and about 15 honeywell dampers) and wiring each application may be different. I called honeywell just to eb safe and confirmed the wiring. It works!
