Desk arrived quickly and set up was a breeze for my 14 year old.  The price cannot be beat - why didn't I purchase this sooner?  There are 4 presets and the desk moves up and down very smoothly.  I like the added hooks on the end for accessories like headsets and the basket underneath to hold the wires.  I just got it today so can't speak to the quality over time, but the price was super reasonable and the desk seems very sturdy.  Love it!
