I use the blades from sensor 3 disposables (I think they are called custom plus 3 in US), for some reason they are cheaper on the disposables than on their own, great shave!
HB is the only razor where I can go ATG all over without any irritation. I use Gillette Sensor 3 blades. Cracking tool.
My HB was delivered less than an hour ago. I used it right away. I am impressed with it however I missed several spots first time around. I did have difficulties right above my ears, but I am sure I will get better with it the more I use it. I didn't even nick myself.
All in all I give it a very high score.
Practice makes perfect my friend. It's not a race, take your time and you will master it in under a week. Good luck.
I want to try out head blade. It would be awesome to see if they could get a product that uses gillette fusion 5 blade. that would be an awesomely close shave right there.
