I found this product to be a good purchase. It arrived well packaged, and was easily assembled with the tool provided. Assembled product is well crafted and sturdy. Our "boys" are a fluffy 16 & 12 lb "Pound mutts", so my only complaint is the upper platforms could be bigger by 3 or 4 inches. The cats do enjoy it. We put it by the window in our home office, and they hang out watching the wildlife outside.
