I think Simon and Syril has been using some
I saw a video review of it, along with other substrates, that was very positive and supposed to be a lot better than Carefresh, good texture and not dusty. It's described as wood pulp, the same as Carefresh, but presumably a different kind of process if the texture is different. I was tempted to try it but then found Fitch and am happy with that so never got round to trying it.
