I recently moved into a house that did not have a basement or a place to tuck away a litter box. Previously, I used two of the newer Littermaids in the basement for my two adult cats. Concerned about the odor and tracking, I wanted to try this cabinet. I currently have it at the far side of an upstairs landing. With at nice, comfortable pad on top, my cats now have their own little area. Regarding the smell reduction, in the summer, I left a window cracked and as long as I kept things reasonably clean, there is no noticeable odor. Now that the windows are closed, I do notice some slight litter box odor but I just keep a small HEPA filter running and the odor is gone. This box does greatly reduce the tracking. The only downside for me is that the interior drawer front came with a huge gouge in it. Since it does not show, I left it alone.
