I used to be a dedicated DE shaver; once I grew a beard, I started shaving only to clean my neck and cheeks, and decided to try cartridges again. So I tried Harry's. And man, I wanted to like them, but a Mach 3 blade is just so much better it's kind of dismaying. The Mach 3 (i.e., three-blade head) is smaller and more maneuverable; the blades seem sharper, or at least certainly glide more smoothly with less irritation; and there's actually a bit of an ecosystem around them -- I'm using a Parker handle with mine, about $30 but better than (the admittedly good) Harry's handles.

I'm glad Harry's found a nice exit, I guess, although on general principle I wish they'd been more invested in staying independent than they evidently were.
