I’ve cut my own hair since 1993 using a Flowbee. I am still using the original unit and the plastic spacers although I ordered a second set when one of them cracked about 3 years ago. Am still using the original spacers though.
I get great haircuts but need to use a set of clippers to trim the burns and back side at the neck. That is a hoot since I have to hold a small mirror with my back toward a large mirror in the bathroom. Takes a time or two to get the clippers in the right position looking through two mirrors.
I do get an occasional compliment on the cuts and several have asked who my barber is. All it takes is a bit of patience. It really is easy to use. It surely has paid for itself many, many times over.
Jeez, we posted at the same time and said very similar things. LOL
