Bests & Worsts Reviews from Amazon

The other night my wife and I were quietly talking in one of the usually unused back bedrooms around 9:30 PM when we heard the distinct tone of a cell phone right outside the french door! It is a shock to discover how easily your space, your life, can be invaded. That only happens to other people, in bad neighborhoods! I immediately started looking at motion triggered lights on Amazon hoping the technology has improved in the ten years since I bought and laboriously installed two different lights with totally unsatisfactory results. The Dorcy, especially at the relatively low cost, had good ratings here so, I ordered one from Amazon. It is a nice size and looks nice. Set up was absurdly easy, especially compared to the expensive wired-in units. I mounted it temporarily then set out to test it at night. The detection is spot on from the sides I would expect an intruder. As others have stated, the light is startlingly, surprisingly bright! If I were an intruder hit by it, I would certainly take off. I'll update this review after 6 months use. EDIT I wouldn't change my previous review. Still very satisfied. And the batteries are still going after 6 months. EDIT 8 months out the light started cycling on and off. No idea how long it had been doing this. I took it inside in a dark room with nothing moving and it still malfunctioned. Still on the original batteries though. I'll try to take it apart to clean the sensor. EDIT 11/2/12 New Batteries did solve the cycling. EDIT: June 2013 Still the best motion sensor light I've used. Edit: April, 2014 Batteries last quite a long time actually. We have an active population of night critters here, the usual urban opossums and racoons. A large flood control reservoir (about 2 by 2 miles) a block away harbors a lot of wildlife and an occasional wild cat and coyote have been seen in the neighborhood at night. For a while one or the other was killing and eating small pets left outside! Anyway, the light gets triggered a lot. I bought another brand light and it does the same thing, as does a motion activated back porch light. Of course when I look out I can't see anything. Still satisfied.
