This product was on sale and had some good reviews. I'll never know how well it could have worked because it came without the 'bait' which is actually part of the system because it is part of the complete trap and its weight is part of the overall trip weight balance and it is one of the capture walls of the device.The device supposedly came with instructions, also not supplied, though I do not think they would be necessary other than maybe the warning: "Must come supplied with bait"Not only a bit of time waster, but has poisoned the brand name for me.
