Query: not electronic, but extracts lice!

I was initially annoyed, because of the packaging, which plays on the rumors of an electronic louse comb. This one is NOT electronic. But it is the best comb for removing lice and eggs from a head of hair. It'll still take you an hour or five, depending on the amount of hair. I'm more likely to just shave heads, and be certain that the lice problem is taken care of, but for those myriad who find that anathema, this is the best comb out there. Good luck!
