I'm about to order one of the two, but I can't decide which. Any opinions on which is more useful for our purposes?

Robocut: http://www.haircut.com

Flowbee: http://www.flowbee.com

I can't comment on the Robocut but I do own a flowbee and can say that it is a good solid product that works well.

The only caveat is that these devices don't allow you to cut the hair very short at all so if you have a shorter style then I would probably not waste the money on either.

From what I gather they are similar. I never tried the flowbee just the robocut. and I am happy with it. Its simple to use and does a nice job.

do you use these instead of a normal haircut with a hair stylist.
