I chose this over other electronic litter box because of it's smaller size. It fits perfectly in the closet and the height is great for Lucy. I've been using it for two weeks and it's perfect. The litter drawer size last about 1 week and she uses it 5 times a day. That's with the app telling me it's full which is great. Odor is not an issue. The bags are easy. Super quiet, I don't even here it even when I sit a few feet away. The only problem is that the ball creates static and I noticed that she gets litter stuck in her fur from static. Not a huge issue but she does carry it through the house and I find it on places she lays around. Not a huge amount just dustings of it I don't know how to stop the static. Otherwise perfect in every other way. Also a plus when I did have issues customer service was always right there and very friendly. I appreciate that they made me feel like part of a smarty pear family not just another customer.
