It has a superb traditional design and does the job well. However the force with which it releases the claw is dangerous and can even break fingers so rest assured there will never be a Rat smart enough to enjoy its meal on this plate. Ensure you are placing the bait under the lever of the trap, coconut is suggested bait in instructions but any chocolate, cheese, bacon etc is going to work. The key way to catch the rat is to provoke the rat to put his mouth under the lever.
The spring action of the handle is powerful! Death is instantaneous for the rat. Trap release trigger at back releases and reduces risk of trapping fingers when unsetting the trap.
