Bests & Worsts Reviews from Amazon

I really liked the specs of this item and bought two from Home Depot (several variations of the same can be found in Fred Meyer and other stores). As couple of others have pointed out, it doesn't turn off at dawn in the dusk-to-dawn mode, as advertised I did some experiments indoors and it turns out that while it can turn on correctly in low light conditions, the logic is faulty in detecting ambient light while the light is ON - perhaps it is a difficult problem. I contacted the Company via email and they confirm it will not work if the outside is cloudy - which is most of the time in the Seattle area. I tried to use it in the 8 hour mode recently, but even that seems to be faulty - it works for about a week, and again does not turn off after 8 hours. I hope the company can fix this annoying bug.
