I really like this. It beats using a plastic grocery bag every time you clean the litter box. Very convenient. It sits right next to the litter box. No odors. Has a razor like cutter inside that cuts the bag each time. You just tie it up and dispose of it..

I got the xl refills with the box and I've only cleaned one litter box about three times and it's almost full. It does not hold much litter and it gets stuck going down halfway. It makes scooping litter a hard chore now
