The following inquiry represents the kind of minutiae you never saw in print, or even heard aloud, before the Internet:
So I've been using an injector for about 2.5 weeks, and I love it. I couldn't believe how simple and close the shave was, and the Chinese blades are top-notch. Today, though, I was on the road and I used a fat-handle Tech I brought with me. And the shave really wasn't that great. Not real close, yet I risked irritation if I went any closer. Two theories:
1) Techs just aren't that great for me: I last used them a few months ago when I was picking things up and this is the kind of shave I usually got. Other DEs between then and now - Merkur, Slim - have worked better.
2) This is more troubling: could I have become dependent on the Injector?
Anybody else on this site become Injector-dependent and lost their DE chops?
