I bought the Christopher Bradley with included C plate. I figured I'd get this D plate just in case. I used the C first. Very mild, but quite efficient. My next shave changed out to this D. Wow, it was perfect! Still very mild, but a lot more efficient. I was able to do a 2 pass with a little cleanup for a perfect shave. For the price, might try out the E next. And the shipping at WCS is so fast.
I thought the C plate was great, but decided I wanted to try just one step up. I am thrilled I did. The D plate (with Astra Green or Gillette Black) gives me the closest shave I've ever had in only 1 pass. Granted, I am not striving for the BBS shave anymore, but this very close and with being complete in only 1 pass there is very little chance for irritation. My beard is very coarse but not dense. I don't know if it would work the same for you, but for me, it just might be the Holy Grail in my shave den.
The dimensional tolerances are very precise, the brass sandblasted matte finish, high quality, very delicate and beautiful.
