My wife and I have been considering this litter box for a long time. We have three cats so we constantly deal with buying litter and/or supplies, and cleaning the box. The price had always put us off, but after taking a look at what we already spend, we decided to take the plunge knowing we could always return it if it wasn't a good fit. We were excited when it arrived, and impressed at how easy it was to get set up and ready for use. We have been using it for a few months now, and I can't ever see us going back. The price of the Solution and Granules is less than we previously spent on litter and box supplies. We did invest in the SideWalls, and good litter mat because we did find the Granules pretty easily followed them out of the box. Those two things cut down dramatically on the amount we find around, and the ones in the mat are able to be dumped back into the machine and washed! Never in my life did I think I would say I love the smell of my litterbox, but it's true! With 3 cats we'll see how it holds up over time, but I can't fathom going back to a traditional litter box.
