Easy assembly and worked perfectly from the get-go. I don't tend to move it up and down much so I can't speak to that but I love it was perfectly adjustable for my height (5'3") and fits two monitors easily.
This stand desk has helped with the feeling of being lazy with sitting all day my posture is better and it has helped with my pain in my hands from straightening my body.
The desk is easy to use and assemble - pretty much ready to go. It does not a large surface and most computer desk will not be large enough and can hold/support the desk.
