The desk does take a few hours to assembly, and need drills to install cable tray and drawer. But once the hard work is finished, the table provides the most smooth and flexible experience.
My new Flexispot E7 is amazing! It was pretty easy to put together; lining up the holes with the top piece was a little challenging, but for the most part it was pretty easy. I am using it now and really like the ability to be able to stand up while working.
