I bought this item to put the bowl above my cat for her to come eat & drink in the kitchen at night (not ... despite what is said in any case my cat seems being able to see in the dark!). It was very effective and I was delighted! The sensor, set to 30s, was very sensitive and flashed instantaneously, remaining on as he felt a presence of about one meter (or advantage) from left to right, up and down (rather broad spectrum so). Unfortunately, almost exactly two months later, nothing! The light is first blocked ... will light up when she detected a presence but are off more, and whatever the setting (30s 60s etc.) Finally, two days after it was lit at all, even with the button manuel.J'ai tried to clean everything very carefully, thinking can be the location (kitchen) could cause clogging of the sensor the nvapeur, grease etc. It changed nothing.
I am very disappointed, I fear that other dissatisfied posters are right, it is simply a Chinese unit of very bad bill / low quality, not built to last despite a far from intensive use!
