I used it today and shockingly, it did a great job. It did exactly what it was supposed to do. My style did not change but the ends were in the little compartment that catches it. I even looked at the little hairs myself and saw that they measured 1/8 th of an inch (like they promised) and that it got the bad ends. (I really needed a trim! there were a lot of hairs in there.)I went over my entire head sectioning off small parts and going over the parts 2 times. I followed the instructions and it worked. The only thing was that i had product in my hair although it tells you not to have it in your hair (but only enough to give my hair some slip. It was not wet or greasy so the bursh can go through smoothly) When I finished, I sprayed my hair with surge.
The only bad thing is getting all the little hairs off the blade. (cleaning) I dont want to cut myself or mess up the thing so i just shake out what I can.
I got the hang of it so now that's one less service I will need from stylists. I know some people are having a hard time with it but it is working fine for me.
By the way, I started using surge on monday and I am not shedding as much as I was so I can't wait until 14 days to see how much my hair has improved.
