The one that works with the sensor blades is the black one as Tyler filled us in on the thread.
If you buy the HB sport at CVS or Walgreens, it comes with an adaptor(black) and a sample tube of headslick.
I will say here that I am a die hard atra plus fan. But the triple that came with my headblade sport was alright, for the first two shaves and then it felt REALLY dull. Not as in drag, but it just wasn't cutting anything.
I absolutely hate the Headblade razors. i find they get gummed up to easy, and hard to clean.
i prefer the sensor blades, but my damn adaptor broke. I'm oging to have to order some but i'm waiting til i deceide what else i want to order with it.
There are some Shoppers in Halifax that now carry a range of HB products bro
