I used the Dorco Pace4 yesterday. As far as cartridge razors go it's pretty damn good. I got an extremely close shave. So close in fact, that I skipped a shave today. It's pretty much up there with the Gillette Fusion Flexball.
The handle is sort of rubbery, with plenty of grip, giving a nice balance. Does anyone make handles like this that fit DE heads? (Heresy! I know...)
On the downside... it's a cartridge razor and therefore boring.
There are still free razors (just postage) available ↪here. Bargain.
