I have to say, one of the b st purchases I've made in a while (and I'm an Amazon junkie---everything (literally) I buy, or 95%, come from Amazon). I'm happy with most of my myriad purchases, but this is one of those rare, every-is-what-you-hoped, no complaints purchases.Here's what I expected/needed, ALL fulfilled up to or beyond expectations (or even hopes: ex. easy assembly?):1) Dual, sit at desk, or work standing2) MULTIPLE settings; not sit/stand (there's 10)3) Solid construction and feel at all heights4) Simple enough (i.e. just what you need)5) Versatile portability, even loaded with gear6) Easy, minimal steps, intuitive assembly7) ALL necessary hardware, INCLUDING tools8) Wheels move easily and they LOCKThis thing is great...simple design, yet stylish, SOLID, and the Ben though Spartan, still has four shelves:1) Upper/top--monitor, if necessary2) Laptop/keyboard, mouse (work area)3) Smal middle miscellaneous shelf;4) Bottom shelf: power, CPU/Tower, etc.One (slight) negative: not a lot of extra desk space (width). But you shouldn't often be using as your entire office. However, if you are (efficiency apartment), there's enough space to make due. Especially with four shelves. (And recall, I use it with my laptop; if you only have a keyboard/mouse on second shelf, there's significantly more space leftover.What do I end up using it most for? I leave it in the most trafficked room in the house (living area/kitchen/etc.) in standing position. Great for those moments of walking through room suddenly thinking, "Oh, I forgot to jump online and _____". Don't have find device, sit down---just walk over, type it in, walk away.Suggestion: Do as much "standing" prolonged work as possible---comfortable (automatically good posture, no tendency to hunch), great core strengthening (especially for me--Inhave a long torso, ergo lower back gets sore (weak) when I have stand a long time), leg workout without even thinking about it.If you're looking at items like this, you've scored a multi-nugget: portability, sit/stand workstation, solid, fully adjustable, and decently priced.LOVE this thing!
