The zapper works, catch both mice and rat. The problem is it just broke less then a year of use, I clean it and use new battery, the red light is blinking, the bait is gone, the rat is having a free lunch, after several nights having the same thing happen I know the zapper no longer works any more.A trap cost so much and last so short, very disappointed, another bad experience with stuff made in China, they always go bad after a very short use.I am searching one that is made with better quality, any suggestion?
