after hearing about how fabulous the mach 3 was, i was anxious to try the women's version but i was so disappointed with this razor! first of all, the refills are WAY too expensive- around $15CDN for 4, i believe. also, my legs didn't even feel smooth right after shaving (and i used Gilette shaving gel for women, too). then, because of the three blades (cutting deeper below the skin but somehow STILL not making my legs smooth and soft!), i found that i had more ingrown hairs to deal with. the only advantage was that the next-day regrowth on my bikini line didn't seem as bad as usual, but the disadvantage of the ingrown hairs alone outweighs that. i'm sticking to the Sensor Excel for now.
