I've been using this nearly every day for a month or so. The scent isn't quite like the cologne (not quite as piney), but I find myself giving the mug a sniff anytime I'm in the bathroom. It's made with both tallow and vegetable oil, and the lather seems to be a cross between Harris and T&H, in the best possible way.

In a moment of weakness yesterday I ordered 5 pucks from Penhaligon. If my math is right I've now got 4 years supply of the stuff. And I'm worried that it's not enough, that I should have bought another 10 pucks just in case there's a dreaded reformulation...
