I've been shaving with the much lauded EJ89lbl for a few months now, and have figured out pretty much how to get a great shave every day (knock on wood). About a month ago, I bought a Tech on the bay, but was scared to use it until I was secure in my chops. Today I tried it and here's what I noticed. It seems to be more sensitive to the blade angle -- that is, the range of angles within which the blade cuts is narrower than with the EJ. I got a good shave using the same Astra I've been using, but noticed a couple of spots that aren't quite as smooth -- where my angle was wrong. Still, in going to keep hitting it regularly, while I wait on my NEW!
