It's very easy to bait and set up this trap, and it does indeed catch mice as advertised.  My only hesitation is that I felt the mouse was more terrified than it might otherwise have been because the trap is completely opaque and enclosed, unlike the wire mesh Havahart trap.  I was awakened by the tiny noise of the mouse running back and forth in the trap, thereby rocking it up and down, and after that went on for an hour, I finally got up at 3:00 a.m. to drive several blocks and release it!  May sound silly, but if you care enough about not killing a little critter needlessly, you might also care about its terror level, as I did!  Ultimately felt more comfortable spending the few extra bucks for the wire mesh trap.
