Buzzed my own about a month ago. About to do it again. Easy to do. Mine grows like a weed, so I figured if I screwed up badly, I'd just wear a hat for a few days. Didn't need to.
I was thinking that someone should start a NetFlix style (original NetFlix, not streaming), where guys just pay $5/month, and periodically a device shows up to buzz your hair. You then clean it and send it back.
'Course, the actual device is only $20-30, so it's not worth it, and my idea died on the vine, as they all do. But it was a funny thought, to me at least.
