Review on Sensky 360 Degree Ceiling Mount Occupancy Sensor - High Sensitive PIR Motion Detector, 110-240V Switch, 6m Max Detection Distance by Mike Groover

The motion sensor works fine. I put it in the closet because my wife never turns off the light. The sensitivity setting and the timer setting work for what I need. The light comes on even if the area is already lit, and turns off about 2 minutes after it no longer detects movement. Instructions are a different story. I really wish the Chinese companies that make these products would hire someone who grew up speaking English rather than someone who speaks English as a second language. It took me a few minutes to understand what they were trying to say and understand the schematic well enough to install the switch. Once I figured it out, it was pretty easy to install.
