Great traps.  Didn't get a ton of use, because I caught a mouse when I thought I had rats (the racket they were making, it was such a surprise it was only tiny mice).  But that's a big positive for these, because if the trigger is sensitive enough to go off from the touch of a little mouse, then it's definitely going to get a rat sticking its fat schnoz in there.  Other trap brands I've used won't go off when the rodents lick the bait off of the trigger.  These ones are the old dangerous finger breakers, but they work better than anything else out there.  Just learn how to handle them and you'll be fine.
