Well, they work!

I have used older versions in the past and they have worked well. This one, well, lets just say it doesn't. It appears to set like older versions, but we recently had an uninvited house guest enter and due to some renovation work, has become trapped inside. The only thing these traps have done is make it a convenient dining spot for our not-so-welcome, furry little friend. The sensitivity seems to be quite poor. Several times the mouse has been able to steal the bait off the trap without tripping the mechanism. I surmised it was a Ninja mouse and was able to contort itself and reach over the sides of the trap to retrieve its well earned reward. I built a small structure around the trap, so the only way in to reach the bait was to approach from the trigger mechanism. Once again, the bait was gone and trap was not sprung. So, either this product is garbage, or our Ninja mouse climbs like spiderman and dangles down to plunder the trap. Find another option. (Glue traps are just as bad, the mouse just avoids them.)

Worth the money!! These traps are great,!

Hey it works, the mouse didn't get the cheese. Instead the mouse is in mouse heaven, what more can I say.
