Wow the first time i did my legs it took about 4 hours. the few months after that I have terrible ingrowing hairs, no I can do it easily in 30minutes ever fortnight and have no trouble at all. I did try it on my face and it nearly ripped the skin off, not a good plan. Anyways Id's say persistance is the key. I use a Philips satinelle soft, it has a really useful roller.
