Great product for kids and adults!
Our 4 year old wouldn't let us cut his hair no matter how much we bribed him.  The electric clippers are scary for kids and using scissors freestyle is just not going to work.  The HairFin is amazing for little kids!  He was very intrigued by it and let us cut his hair multiple times already!  I don't know what we would do without it.  I have also used it on my own hair and my wife has cut my hair with it as well with great results.
