(More customer reviews)I have installed a couple of these switches, and they are not just plug-in and forget. The mini-manual the comes with them gives details, but in chinese-english that is hard to understand.
(1) Setup - There are two small thumb-wheel controls beside the motion-sensor. The one is for setting the length of time the switch is ON, and is obvious. The other one is quite delicate and compensates for ambient lighting and the lighting of the moving object. This is especially tricky when the motion sensor has a window in its view, and the ambient light it sees changes from day to night. If you have a window facing the switch, it would be best to put a blind in it to filter out some of the ambient light changes. With patience, I was able to get the switch to work well even though it faced a window. But it takes trial-and-error to compensate for motion during both day and dusk (it doesn't work at night).
(2) Flickering fluorescents - With the widespread conversion to fluorescent lighting, there is a new problem. The small screw-in spiral bulbs that replace incandescent lights have electronic "ballasts", which are totally different from those on the long fluorescent tubes. This motion-sensing light switch does not go completely OFF when there is no motion. A sensitive VOM will measure about 30+ volts on the hot line. However, there is little current available. The 30+ volts is enough to trigger the ballast on the spiral fluorescents, and it tries to light the lamp, however there is not enough current available and the light tries to go on, drains the minimal charge on the line, and then goes out. This repeats and you get a flicker. ---- You can solve this by replacing one of your lights with an incandescent lamp. This will constantly drain the charge trickle through the switch and prevent the voltage building up to trigger the ballast. I have used 45W and 60W bulbs, and both work. They just go in parallel with your spiral fluorescents. And you should no longer have any flicker.
**** With careful installation, these switches work quite well. My wife expecially appreciates the one in our laundry room which goes on automatically when she comes in with piles of laundry (we have a traditional marriage).
