Review on Maxsa 48219 Battery-Powered Motion-Activated Wall Sconce with Golden Copper Finish by Srinivas Johnson

I've bought 3 of these over the years. The first was excellent, served for 3 years, always worked perfectly until one fine day it just died. The second worked for about 9 months, then the sensor stopped working properly and kept turning on and off all night. It was still under warranty, but you have to pay shipping and it's heavy, almost like new. Tried swapping batteries for other brands, didn't help. The third was broken on arrival, never turned off and the sensor was dangling from the bottom until I put it in place. The idea is good, but technical help is needed.
