This is a great cat track system. It looks nice in our house and the cats really love being able to get up higher than a regular floor-standing cat tree. The price isn't too bad, either, compared to the more expansive floor-standing ones. My cats are 17-20lbs and this track has no problem holding them up. It is a bit noisy on the other side of the wall when they jump on it, but I don't know that I can fault the system; just be conscious of where you mount it.My only major complaint is with the mounting hardware. The included screws were kind of short, considering that they often need to be drilled at an angle into studs. Also, unless you have a long extension drill bit, your driver will be at an angle and the included screws are prone to cam-out and stripping. I put in a few of the included ones and then switched to some premium torx head construction screws. The brackets are difficult to get a good angle on because they are narrow, but such is the price for a sleek design.Pros:- looks great- lots of height for the money- cats love it- not too hard to install- doesn't take up floor spaceCons:- can be noisy when large cats climb on it, depending on wall construction- The finish on the boards was a little rough. It seems that the stain raised the grain and they didn't sand afterward. This is a minor nitpick and maybe unique to one batch.- Expensive, but not much more than a large free standing tower- Included mounting screws aren't greatTips:- get a long extension bit for your drill/driver- spend a few $ on nicer screws at the hardware store- use a laser-level for alignment- the canvas is tight, but will stretch
