Bests & Worsts Reviews from Amazon

I purchased this "Cat Climber" (strange name for a desk?)* a few months back and attached it to a rarely-used door off the living room. Assembly was a breeze, its a very simple design yet very sturdy once installed. I'd recommend to pay attention to where you're going to install it and make sure the door-knob-level shelf is facing *away* from the doorknob, especially if you have lever-style door handles like we do. It's not the end-of-the world even if you don't, but I wish someone had pointed it out to me before I assembled it. Installation took a little more effort since we have high ceilings and tall doors to match so it took some elbow grease to fit the tension springs over the door and door handle. It would have been easier if we'd removed the door handle first, but in the end it wasn't necessary. It fits securely on the door and takes up very little space. Usability is great, the second-from-the-top shelf is perfect for a monitor or laptop, and the self below it is nearly ideal for a keyboard and trackball/trackpad. Each shelf is a hair over 17 inches wide and 9 inches deep, however there rear support is around 1.5 inches thick so you can't use the full depth (only about 7.5 inches). My laptop protrudes slightly from the higher self, but I've found it to be perfectly stable. I often also use the Aidata aluminum lapdesk to raise it up a little, but its not needed. I have a 17" monitor that would fit well there too, and I've found that the shelves do not sway and in the months I've used it, nothing has fallen off the door even when seeing traffic back and forth. On the lower shelf I use a Kensington Trackball with Scroll Ring (available here on Amazon) on it and I find I need a wrist rest, but that's mostly due to the design of the trackball - it wasn't made for standing desks - but its easily remedied. I also have a 60% keyboard (no arrow keys, no keypad) next to it which fits very nicely (Matias, Happy Hacking, and others make keyboards of this form factor) . A full-size keyboard is going to eat up a whole shelf, but you can get a mouse tray also from Aidata here on Amazon for a few bucks more if that's your preference. I put my speakers on the very top shelf, and if you run the cables down the hinge-side of the door there's no worries about the wires getting in the way or pulling anything off the shelves when the door is in use. Overall I'd say this was a great purchase. The best part is that I don't have to worry about the cat climbing over my keyboard at every opportunity. * Yes I know this is a door-mounted cat tree, however, the cat didn't like it. Only sushi would get her to even the second shelf, yet she always finds her way up onto the kitchen cabinets. Over the weeks that followed I found that it made a great standing desk, hence this review.
