I was thinking about having a number 2 on my head, but if I don't get the angle right, it could be messy.
Same for me, splashed out on some expensive Babyliss clippers about 8 years ago (were about £75 at the time) ... have probably saved me best part of £1k in that time and still going strongI joined the Wahl clipper club years ago. Not seen a barber since. Honestly it is easy. I do it myself and the wife just tidies up the neck-line.
