Received this box to try out. Out of ther box, it's an easy set up. Was surprised that it wasn't a one piece unit, in that the actually tray that holds the litter crystals is disposable. One of the cats has soft stool issues and was surprisingly the only one to take to this box (the other two just like watching it in action). The biggest pro is that the crystals do wonders in odor control! Unfortunately, the clean-up is not that great in that the "remnants" aren't being scooped entirely and constantly get stuck to the rake, which then has to be cleaned.

The biggest con is the cost of upkeep. I have researched the cost of tray/litter crystals refills and it's more than what I have paid for waste cartridges on my other automatic box. 

That being said, I would still recommend this product.
It's a great product, but it just doesn't hold up to the demands or needs of the cats in my household. [This review was collected as part of a promotion.]
