The case works well, a bit problematic is the hanger (metal hook) because our house mice (in the last 4 weeks 18 pieces caught) all big fans of chocolate cookies, and you get no tricks with frosting etc. not tuned stuck / hung. The event is sold partly as a rat trap, partly as a rat / mouse trap. I had this case been purchased as a third case, because another live event (with the tilt mechanism) 18 failed and a Totfalle of mouse No -.. Mouse # 18 has itself the Totfalle (3 times been successful in other roommates) triggered and came out alive (with chocolate cookie, of course), and even the tilt mechanism of the already 14 times successfully BEEN livetrap they overcame (with chocolate cookie, of course). The Luna case was also stocked with chocolate cookie, and what shall I say: to flap, chocolate cookie path, but: Even mouse away. We believed already to a mega-intelligence mutants, but have actually filmed using a mobile phone camera, the phenomenon: the very young, very intelligent mouse was so small and mainly articulated that they by about 1 cm measured squares of the wire slips past is !! We have indeed laughed piebald, as we have seen captured on film the deformations that mammal - but has helped us nothing. So, absolutely great for larger animals, not suitable for definitive animal friendly solution of a plague of mice. Ultimately, unfortunately, had to prove their Totfalle service - the live traps have available the intelligent animal can not catch.
