I absolutely adore this kitty kondo...and my baby Kissa loves it, too!
He plays on it, sleeps on and in it, and obviously uses the litter box that is wonderfully hidden inside the cabinet.
Its affordable as well as a solid piece of furniture. We put it in front of windows so he can still enjoy the sunbeams. 
The best part of it is not having to look nor smell the unsightly litter box. I certainly never believed I would have a box in my living room!
If I had to say one bad thing about it, the surface of the upper cabinet, below the peekaboo hole, is slippery. I purchased a kitty litter mat, cut it to size, and attached it with double sided tape. It works very well and gives Kissa the courage to jump to the upper levels, which he now loves. (Edit I wood glued the sticks with the balls became they became loose...Worked perfectly!)
Top notch product and I highly recommend!
I hope this helped!
