sensor range is kind of short. it doesn't seem very bright. it turns on during the day time as I was installing it. sometime at night one of them would turn on but the other one remains dark. Wayfair seems to constantly bugging me to review it, like they want me to write a good review before I had time to find issue with it. You kind of need to use solar power items like this for a minimum of 60 days to know if it works properly and I just got this  less than a week.
