The traps generally work already. However, it requires some adjustments before it snaps properly. First of all I had the traps simply erected equipped with Nutella. The result was that the bait was completely weggenascht that traps but not triggered. Then I made times with a screwdriver snap some experiments. As a result, you have to find that everything to rat size on the release rocker could perform a tap dance without running the risk that the event triggers. The actuating wire which is pushed into the Wippöse is too strong bent backwards. The eye is literally pushed backwards. So you have to significantly bend the wire to the front, then I even angepfeilt a bit, so that now no longer remains already licking the bait without consequences. Otherwise, the case is solid and easily installed. Conclusion: For the price you get a simple and good quality. Thus one also catches the pests are necessary adjustments to the securing hook. Then "folds" it as well.
