have to rely on the many positven reviews, the price is also really great .. also feel great, I have to say. hair also do not fly out but the smell does not go .. the bag and each brush perpetually smell chemistry that does not want you to do it in the face. I washed it with shampoo, only the smell is still not away .. very very uncomfortable, I must say. but what sollts, I'll keep them, have hope that goes away after a few odor washing units.
