I've only caught one mouse but the trap has been used a few times by clever mice that can get in and get out after dining. I've only had the trap for a couple of weeks so I'm not giving up yet. My hope is the mice will get a little fatter and not be able to escape.
I've had these (4) up for over a week. I've baited them with different items and have trapped zero mice. I can see evidence of mice in my home. Very good construction. Make sure ramps float freely. I'll give it another try with some other bait and see what happens.
