Matte head arrived a couple of days ago. Must have come by air rather than by sea - a little over a week since ordering.
So far I've had a couple of shaves using a Schick Proline. Or rather 1.5: it's so bad I couldn't even finish the second try tonight. It feels rough, a little tuggy, and it doesn't cut very close. I find I have to buff repeatedly to clear a spot.
Halfway through I gave up and picked up my Merkur 985 (the open comb travel razor). It was whole a different league of smoothness and efficiency. No repeated buffing: just long smooth strokes.
Might have a go at grinding down the front lip of the baseplate to expose more of the blade. Out of the box, it's the kind of razor that makes you want to grow a beard.
