What I personally DON'T like about the sport model is the cheapness of the wheels. I have been shaving twice a day for ALMOST a week now, and my wheels are getting kinda wobbily.
I have it on good authority that the Clear HB Sport will be available to the public, just not sure how soon. I'm thinkin' that being clear, the hairs won't see it coming and try to lay down before they're chopped off so you'll get a much closer shave!
