It has only been operational for a week and too early to rate it 5 stars. Everything seems to be working except for the lightning sensor due to a lack of a storm to give it a test. The display is outstanding compared to my similar older unit which we considered good. The outside unit was still operational when I removed it after approx. 5 years. My concern is the longevity of the display but if it lasts as long as my old one, I will be happy. We put the old outside unit in storage as a back-up in case the new one goes south after the warranty. It communicated with the new display for a few days until I got around to installing the new 5 in 1 outside unit.
