I have been using this one on my then 4 and 1 year old boys since four years
ago. I think it is a good product, making less mess. But there are still
hairs to be cleaned afterward. It makes louder noise than regular hair
clippers because of the vacuum. The litter baby might be scared by the noise
. My boys get used to it.
