Immediately received immediately tested. First impression, blah ... This detector is a bit "Quincaille" and the batteries supplied with the latter does not really seem to load. After reading the manual (in English) and follow instructions, I test. Verdict, the infrared detector does not detect anything. I turn the original batteries (Made in China, with more than outdated technology NICA) and replaced by Duracell NiMH batteries 2400mA purchased at the same time as the detector. Miracle, it works perfectly .... For 5 days, the cats defecate outside the perimeter of the detector, ie more in my garden;) I recommend but remember to put quality battery!
