Bought the unit from amazon, fitted the batteries (not to bad) knocked the unit on, led lights up, buzzing from the unit, then a click, light goes out and buzzing stops.
With reading other reviews about the units can be faulty, I touched the holed plate, nothing, then proceeded to touch the other plates inside the unit, nothing? A thought popped into my head that maybe 2 plates need to be touched at the same time to make a circuit, again nothing, so after moaning to my wife that it was rubbish, I demonstrated how rubbish it was by stuffing my whole hand in to the unit to prove my point....ZAP, got the full shock treatment!!!!
Anybody not sure if this unit has the stopping power for the largest vermin, worry not, I still have a headache and sore hand!!!
