I've had my Wahl trimmer since JC was only a couple of years old. I've never cleaned or maintained it, particularly. Works great. I used the #4 comb, all over, then cleaned up the edges and sideburns.
JC is lucky (?) enough to have two cowlicks on the back of his head, plus one near his forhead, so this side of his hair looks a little funny because of that. And no, I didn't cut two bald spots, it's how the hair reflected the flash.
I think his teachers and friends aren't going to recognize him tomorrow. Can't wait until Rachel donates hers to Locks of Love. We have to wait until after the dance recital since it has to be in a ponytail. Maybe I'll buzz William tomorrow. Let's hear it for low maintainence!
