I liked how easy and straight-forward the tower was to assemble.Finished unpacking to final assembly in less than 10 minutes; no tools required. Pieces snap together. Read the instructions first. Once snapped together the manufacturer says the parts can't be disassembled!The two storage bins have plenty of capacity for storing treats, food and pet gear. I'm using mine for treats only. The bottom bin has a maximum weight storage of 8.8 pounds per the manufacturer.I like the tower's slim profile. In my small apartment, the tower fit nicely by my front door.Dislikes? The top lid to the bin, while it has a good fit when closed, is engineered poorly. You'll need one hand to open the top bin (bottom bin smartly has a foot pedal), another hand to open the lid, and a THIRD hand (?) to remove the bin's contents. LOL! The lids should snap in permanently and have some sort of brake that keeps them open as you need.The tower comes with two hooks. It should come with four hooks. Each side of the tower, left and right, has two places, top and bottom, where you can snap in the hooks. Why can't I use all four hook spaces if I want?The 'hooks' also are not wide enough to hang much of anything. Soon after I took the picture of Hazel's choker collar hanging from the hook it fell down. I wouldn't even call them decent hooks. Maybe you could hang a very thin leash. The manufacturer says the hooks have a maximum weight capacity of 4.4 pounds per hook. It would be easy enough for an enterprising person to install plastic hook hangers you could buy from Home Depot with a cordless drill in minutes.
