I have read about this Robo-cutter thingy on some of the forums. Is this something that actually works and can give a good cut? I saw Michigan Baldy's video and for a flattop type cut, is seemed to work fine, what about more fo a medium lenght hair, aroud 3 or 4 inches? How would the belend turn out? (I gusess you woule have to do that part by hand? I am facinated with the possibility of cutting my own hair!
