i had no luck with this. It is hard to get set and when you try to place it in the ground the trigger springs very easily causing you to have to reset it and try again and again. I also caught no moles i think primarily due to the locations i am trying to catch them. I don't see any long straight runs like the directions and videos suggest as the place to put the trap. All i seem to have are short round paths (which according to the videos are feeding hunting burrows) i tried placing this in these locations with no luck. I am finding the P7901 mole chasers seem to be working much better. I have placed three of them and after about 10 days i no longer see any activity in the areas (about 100 feet wide circle) from these. Some people seem to have luck with these however so i guess it just depends on if you have the right mole runs to catch them in.
