After using the robocut for about 3 years, I recently started going to a mid to high end salon for cuts and I can definitely see am improvement after letting a professional cut it. Generally speaking some of this may be due to varying abilities of us wearers to cut and style hair but I have to believe that a professional with a pair of professional hair cutting scissors does a much better job than the robocut blades which after quickly getting dull will stretch and tear the hair. There is no way the robocut can produce as good a cut.
I also emailed the salon some mens hairstyle pics to show them what I wanted and had no problems.
When cut with a robocut or thinning shears the hair doesn't move as naturally when blown by the wind because it has that frayed look like the frayed ends of a rope is the best way i can describe it. Whereas cut with good quality scissors the hair moves amd lays better.
