I still have one from BLR (before Litter Robot). It was great. Trapped the smells really well, although I had a lot of trouble with the bags sticking to themselves and I would fly through cartridges because the sticking would cause me to think it was more full than it was, and I'd end up cutting and tying it off with all of this wasted bag in it. But that might be because of humidity and heat in the summer here.

I haven't had the heart to throw it out, since it was very useful. I don't need it at all now. The LR puts everything into its own locker and hides the smell even more completely. Have I mentioned how in love I am with the LR? I'm a broken record, but it's really the greatest cat litter related invention ever. They ship internationally too
