Very easy to setup within minutes. This litterbox is so convenient to not have to scoop any business. The only con i see from this product is the litter itself creates tracking over the floor which then ends up all over your feet but nothing a little sweeping or vacuuming can't fix. In terms of odor from using it for almost 2 weeks straight there was hardly any noticeable. Loved that the button can be used to rake manually is needed just in case. Although my cat was scared of the rake motion at first which was hilarious to watch to try to fight with it, he got used to it. Overall this is an awesome product.
