i am so very happy with my purchase. I have done a total of 5 treatments and already can tell a big difference. My favourite part is the fact that when I see hair growth I can just zap that spot and don't have to wait 6 weeks to go to the salon and pay enormous sums of money. Furthermore, only I know where my "problem " spots are. I have done professional laser for years and the dermatologists or beauticians always give the same treatment all over and never even ask if there are "problem" spots to focus on.
