I received my Epilator today, and thought I would have a quick try and ended up defuzzing both of my legs fully! It took me a while (probably 2 hours with rests for cleaning the epilator) but I have very dark, coarse hair. I think it shouldn't take so long with repeated use. I think the key to less pain, is to use this when hairs are shorter (this is recommended in the instruction booklet). I had left the hair on my thighs to grow fairly long in preparation for waxing, but I thought I would try this out anyway, and it worked well although I think it was more painful because the hairs were longer. I trimmed my bikini line with scissors before epilating and that helped. I did try it very briefly on my underarms but that was tooooo painful, but then I find underarm waxing excrutiating. I owned an Epilady many years ago, used it once, and vowed never to use an epilator again, but I must say that I will definitely not be bothering to get my legs waxed again. I will try and persevere with my underarms (maybe if I get very drunk the next time???). I think if you are used to waxing, you will be able to cope with this, at least YOU can control this. Super product at a great price. I cannot recommend this highly enough.
