The product is simple, cleverly designed. But after a month of use, in different ways, we finally took a little mouse! A month later, with use continuously, we took another. this performance deserves a third star! Other means are more efficient: for example, a spatula balance on the edge of a piece of furniture with a bait (meringue) that, once reached by the mouse, imbalance spatula and dropped with the mouse in a high-sided container (> 60 cm). It costs nothing and it works!
