I recommend it
It hardly produces any dust, but since it's very light, it throws out a lot of litter from the tray. It clumps well, but when it comes to cleaning, it's hard to tell the clumps apart from the rest of the litter, and sometimes they don't form a solid ball, so they break up a bit.
By the way, I bought the 20L bag that Bitiba said was 9kg. That's not true—it's actually 8.6kg as stated on the bag itself!
