This case is the best I've ever used against mice and I have many mice, Independent villa situated in the countryside. The case (the cover) came a little to dent, let himself but true problems. Kitchen paper and put into it a little dry dog food to. I've placed directly in my pantry. After 2 days the first rumble (so you hear when you receive a visit) in the box: 3 beautiful adult mice, a day later 2 pieces. The big advantage: the size, so that nobody gets injured or panic. There are no pinched feet, tails and it actually go several mice voluntarily at once into it. Cleverly created the inputs. Since mice like to run parallel to a wall, to set the trap so that the inputs are hand wall. The price is handsome, but it was worth it to me! Unconditional purchase recommendation. No more snap traps with gruesome injuries or the small box traps, in which is not even room for the tail, which sometimes has to believe in it. When dismissing the prey just cover up and Bye! So, if the case, then this. Sincerely
