Huge +1. I've only had mine a few days, but that's long enough for me to have several hours of honing time on it already. :) I can't imagine not having a slurry stone with the 12k. I'm now getting *very* good results with this stone. Laps with slurry til the DMT scratches are no longer visible under the microscope, then just water for another 100 laps. I did this today on an eBay Boker I'm giving to a friend for Christmas... Bevel set on DMT 1200, sharpened on DMT 8000, then the 12k for several jillion with slurry, then 100 water only. I'm stropping it up for tomorrow's shave right now. The Chinese 12k kinda turned things around for me (in a good way).
Honestly, I can't believe that demand hasn't soared through the roof for this stone.
