The desk attachment is solid, easily supports my two 21″ monitors, the flexibility that the varying heights provide, and the super simple adjustment feature is fantastic. I am now standing at least half of the time I am at my computer, I feel more alert and refreshed. And most of all, $250 better off by purchasing the Amazon version.
