Not just a great price, but this Double Decker Playground is simple to assemble and sturdy enough for our rambunctious kitty.  He LOVES the sisal rope posts and multi-level platforms to bounce around. With so many toys attached, he has hours of fun and excercise. The only thing that would make it better is if the balls for the busy box were a tad larger or the holes in the box a bit smaller so the toys wouldn't fly out every time he plays. One of the balls broke the first time it hit the floor. Overall, we are very satisfies with this product and will certainly purchase more in the future.
