The litter box will spoil you - so be aware of this. The box is great to use and does help with smells in the house. As long as you have wi-fi access then it works great. We made the mistake of going out of town for four days and during that time the wi-fi went out which meant the boxes were in a closed status. Just keep an open littler box around in case the box gets offline. The cost of the box is great, especially since it comes with a one year warranty. Even if you have to replace the box in a year, this is well worth the money. The cats had no problem adjusting to it and sometimes think of it as a toy, especially since it will stop the cleaning process if they jump in while it is turning. Overall a great fnd
