Because of the good reviews I have gained these traps, they have set up and maintained as recommended. Then came the night of hope I've been waiting for that it finally makes clack, it did not but I could see a mouse as she licked with relish to the bait and then made from the field! The next day, the bait was virtually depleted! Besides, I could see like a mouse trap as head used to achieve a higher point, I thought I see not right !!! So to me there is absolutely no recommendation to buy, the bait may attract mice but then should the case also snap times!
