I shave the legs 2 to 3 times a week. I'll admit that it is partly because I race and I caved to peer pressure.
That said, it is also because I get massages every week
, and it is MUCH more comfortable on hairless legs.
Also, I once layed it down going downhill at 40 mph (da*n car pulled in front of me). It was winter and my legs were hairy under my tights (which were shredded). Let me tell you, lying on a hospital bed while they scrub the hair out of a flesh wound for an hour is no fun at all. Henceforth, you better believe I shave my legs year round. :b
Having said the whys of it, I've never found another razor that works as well as the Mach 3. The head swivels nicely and I never get nicks and cuts when applying light pressure. The triple blade system gives a nice close shave.
