works great !!! also with CFLs…read on….. I fool this to work with CFLs without the dance floor flashing effect by including one old style incandescent spot light among the CFL spots in the ceiling.The unit works fine now for over a year in that mode and reduces electric cost by 41%.The old style bulb evidently fools the circuit and the CFLs go along for the ride. The timer is adjustable with a thin screwdriver for the desired “turn off” delay after someone leave the roomIn addition, there is another adjustable screw allowing it to NOT turn on the lights when there is daylight through the room windows. This of course is most useful if the switch faces the window and useless if the room has no windows.I got this one in a local storehttp://www.amazon.com/57884-Motion-Sensing-Switch-Single/dp/B0006JMNJ6/ref=sr_1_2?ie=UTF8&s=hi&qid=1271431639&sr=1-2The Leviton brand did not work in this manner and caused the flashing light dance floor effect; the GE works fine.
