Replaced identical unit. Excellent fit and works well. I am hoping it lasts many years as the previous one didn’t last long. Subtracted one star for longevity.

Mounted this in an electrical box between the light fixture and ceiling above our stairs so the stairs would always have light when dark. It turns on the light in the evening and off in morning. I was concerned it would always be on if used indoors, but it works great!
