I've used it before, though not since I had Comet and Blitzen, it was usually a last ditch option when I couldn't find anything else. It works, it does the job because that's what it was designed to do, but it wouldn't be my first choice. If I'm going pellets, it'll be Back2Nature. I picked up some of Nature's Own paper bedding when I got the wood shavings to see what it's like, but I have it and 6 and a half packs of wood shavings, so it'll get a while to get trying it out.
