I am disappointed by this product. The biggest concern is that it is not working properly: it recharges although the day against by nightfall it tends to stay on at the first presence intercepted ... so it stays on until empty batteries, when it should turn off when no longer detects anyone. Suddenly, everything works the first detection, but then nothing: he does more lights when passing underneath. Yet I have respected the signs: location, height is 1.80m from the ground ... but no, not work! And plastic finish is very slight ... well this is more of a gadget that real product!
