I bought this stone on this website a year ago so I have had time to use it quite a bit. Recently I have bought a flattening stone because my Shapton had lost efficiency. I have to say, after a year of moderate use and an hour of flattening, this stone is as good as new. It cuts really fast and uses quite slowly. As for the finition, it's a 1000 so not a mirror finish but it's a better finition then a lot is 1000 grit stones will give you.
