It's been about three months since I bought this litter box -- I wanted to wait until it was in use for a bit before making a comment good or bad -- and I have to say that results have been mixed for this product. In terms of being a litter box, it works about as well as any other box. But there are a few areas of concern: 1. The litter box, overall, is somewhat flimsy. Durability may be an issue here, especially if it's going to be picked up and moved around regularly. 2. It's a deep box --eight inches deep, about three inches more than my standard large size litter box pan. This results in higher sides, which makes it harder for two of my three cats to get into the box (one of them has basically given up and goes back to her regular one in the other room). My third, larger cat, however -- the one for whom this box was purchased -- seems to like it fine, so mission accomplished there. 3. The deeper box also means it takes extra litter to fill, which again, for me, is a good thing. I can go a bit longer between refills of the clumping litter, which I clean out daily. But we have to go back to the flimsy issue: more litter means heavier weight, which means greater chance of handle breakage or case cracking. 4. This box is almost square -- about 20 x 16 x 17 x 8 deep, compared to 13 x 17 x 5 for my other rectangular box. This makes it good for positioning in the corner of a room (such as the bathroom) -- it fits well against the wall. My cat, a part Maine Coon, seems to be able to pack her body into it without her head sticking out of the box -- a problem with the traditional, smaller, rectangular boxes. 5. There's a detachable plastic door designed to help keep litter odor in the box between changes. Unfortunately, a cat has to know how to lift the door up to be able to get into the box, something my cats have no interest in learning. This would have worked better with a hinged door that freely swung in both directions, like a pet door on your back door or in your garage. I ended up having to take the thing off and leave an open access for the cat, and open exit for all odors. Maybe this works if you start a cat using it when he/she is a kitten -- assuming they can actually climb into the unit. 6. The charcoal litter filter on the top of the box is a standard 4 x 6 size (as opposed to all those custom-sized products for certain other boxes), meaning it's easy to find them in the store or online when it's time for replacement. 7. So far, litter doesn't stick very well to the inside of the pan, which makes cleaning an easy task, for now. Eventually, the smooth surface will start to wear, and I'll have to start chiseling the dried clay off the sides. That should be in about two years (based on daily cleaning). Time will tell. Overall, I give this product 3/5. It's worth the money -- I paid about $25 for mine, and it looks like the price has dropped a bit recently -- and it's certainly worthwhile, given how hard it is to get what is basically an extra large-sized litter box being marketed as large. But it's not the best my pets have ever used in the past 30 years.
