Great for sound-sensitive kids (and pets)
Good for my son who can't stand the loud sound of the barber's clippers. I suppose it takes a little longer to do a cut with these, but my son lets me cut his hair in 1 or 2 sittings instead of 4. No tears, no trauma.  Also, my cat had a matted patch of fur and he tolerated me using this to remove it (!) I recommends this to parents of children with SPD, autism, etc.
