I've just seen an advert for a flea comb that provides a 'harmless voltage' that kills fleas and ticks.
Has anyone seen or used something like this. It says a LED light shows if fleas are present and then you use the voltage to kill the fleas 'instantly'

I've got a real problem with Harry, and have tried garlic in his food, rinses made with Tea tree/rosemary/lavender you name it

but can't seem to get rid of the blighters. I don't want to resort to using chemicals at all and if this works then fantastic.
However I can almost hear my mum 'saying if it seems to good to be true - it probably is....'
I don't want to part with money and find its rubbish or worse still does any damage to Harry or Ben so would like to know if anyone has used one
