I had a dreadful mouse problem at the fishing cabin. Seriously? Crawling on the walls in front of me???? Running around my feet????? Mess...

So, I set about 6 of these every night. Caught several dozen. Caught them ALL so far as I can tell. And NO stolen bait. (Peanut butter, smeared UNDER the yellow thingys.)

The snap mechanism is delicate--I stuck a pencil barely in to see how well they work, and it snapped the pencil. In fact, they snap so hard when a mouse is trapped that they jump into the air by several inches. Clean kills.
Watch your fingers.

I'd use them again.
Oh, and I also set the V traps, but they had the bait stolen, didn't make clean kills and so far as I'm concerned, are just not as reliable.
