Not a bad product,to date I have caught 8 grey squirrels over a period of 4 weeks,it does not always work though,I have seen a squirrel walk in and take the nuts then walk out again without the trap closing,I have fine tuned it so that the slightest touch sets it off as well,I think it is to do with the size and weight of the squirrel when he steps on the trap plate.I have seen a squirrel lift up the cage to get the nuts so I have to put a brick on the top to stop that,they even climb on top and reach in through the sides,so you have be one step ahead of them all the time.Even so I have still caught 8 of them and dispatched them with my gun.
