I have this for 5 months. My cats love it! Mounting was easy, but I had to buy a screw because the one that came with it was not long enough. The bottom needs a protection because it may scratch the floor with the cat's movement. If you have adult cats, it may not be as stable as it should. If the cats scratch the wrong side (like playing with each other), it will get hauls in it because the cover is very thin. Overall I liked it, but minor improvements would be appreciated: a longer screw, protection on the bottom (full coverage), some extra weight on the bottom too and a thicker coverage.
