I was willing to pay, because I have this part of me that doesn't like paying for things repeatedly. That's just the way I am - it's by similar logic that I chose hard contact lenses over soft. As for the razor itself, it has served me well for nearly four years without a hitch. Why other men would find that attractive, I don't know. Mine's been on the same setting ever since I've owned it, although I have tried it out on different settings, and yes, it does in fact make a difference which level you have it on.
Battery life is satisfactory, as well.
If I don't even have to think about it, then it's all good. I have to charge this puppy up only about once every two or three weeks, and that's with shaving every day. The only thing irritating about shaving with this razor is actually my own fault - I always forget to empty it. Then the razor gets clogged and I have to dump a small cat's worth of hair into the garbage. Cleaning the heads is simple and intuitive, though, so thankfully it's not that miserable of a chore.
