Amazing trap. I can catch mice more or less at will. Takes a little time to learn the technique of setting the trap levers, but once you get it it's a piece of cake. I tend not to trap in the bitter cold, since the little buggers don't stand much chance to survive, but use this to clear them out in the spring, and keep them out in the fall. This year I had almost no traces of mice in the winter.While it may be more humane to just kill the mice, I kind of look at it from my perspective. I'd rather have a 1/100 chance in the woods in October than certain death via a conventional trap in the winter.
