Everything seems as advertised. The accuracy is not pinpoint and perfectly stable, the sensed target jumps about within a few dozen centimetres. It's all a limitation of the technology. The static detection is of course not perfect either. But still, the ability to define zones and distances for triggering different stuff makes this more useful than a PIR.
