C’mon people. It’s just $280 for a vacuum hose attachment to cut your hair. Totally worth it
Eons ago (1994?) I went to a professional barber that used one of these (or something very similar). Yes it was a strange experience. No, he wasn’t able to cut my hair the way I wanted. It would probably work well for flat tops and buzz cuts and the like, but as I do not wear those styles it wasn’t for me. After two tries I moved on to a more “traditional” barber. It might be more about skill than the device, but that has been the only time I have seen a professional use one of these.
That said, it was also the only time I have seen a carpeted barber shop.
