Query: Long time Flowbee user

I have used the flowbee system since just after college, (graduated in 1978). I love the cuts, and can't imagine the money I have saved using it. I am a master flowbee cutter now, having so many years experience. This product lasts forever and gives you an exact haircut every time. Fantastic and highly recommended. Great for the kids as well. Only maintenance is a few drops of oil on the cutting blades, recommend monthly.
