I have one of these.
It fits nicely in the hand, and does allow you to contour your head a little easier - However to be perfectly honest with you, it doesn't really do any better job of shaving the noggin than a normal multiblade razor.
I found the design to be a little too easy to over apply pressure as well as your unused to having the blade almost in the palm of your hand
Major plus point is that it can use both Headblade brand blades AND Gillette Senser blades (2+3 blade versions) which on price currently aren't quite as faint inducing as the Fusion blades.
(BTW razor wise i picked up mine in the US for half the price at C&B..).
Its a bit gimmicky tbh and i don't really use mine that often anymore.
PS - Dovo do thier own version, somewhat more elegant than the plastic racing car design. - <!-- m --><a class="postlink" href="http://www.amazon.co.uk/Dovo-Solingen-Head-Shaver-Striglia/dp/B001MJ2ZPG/ref=sr_1_13?ie=UTF8&s=drugstore&qid=1286221786&sr=8-13" onclick="window.open(this.href);return false;">http://www.amazon.co.uk/Dovo-Solingen-H ... 86&sr=8-13</a><!-- m -->
