I bought this industrial version for my small courtyard. It may have been overkill. This thing not only takes down bugs but I reckon would have a good shot at putting the next door neighbours cat into cardiac arrest should it get close enough... or if you are fast enough with a long enough extension lead.An unexpected benefit is the blue glow that bounces off the walls of the courtyard making it brighter than a kings cross shooting gallery.You could also use this outside a flatmates window at night and fake an alien abduction but Im yet to do that so really cant review that aspect of the product.Very happy with the purchase... Im yet to stick my tongue on it to check the voltage but Im pretty confident it is as advertised.
