I absolutely love this desk! I read from a previous review that there is a gap due to the extension piece. I use a laptop and a big screen, so I am at an angle at times, so I use this rug/mouse pad that finally came in handy! Only because when I am at an angle, my arm rubs on the edges. 
In the picture, my husband scratched the top of the desk with the drill. He did haul it upstairs so that I couldn't be too upset. It is heavy, and he assembled it upstairs. The assembly is doable and easy, "if you follow the directions." The screws are in assigned baggies, and all the pieces and screws were accounted for. 
I use 2 laptops (work and personal), along with a monitor, it is just what I needed! I work from home and working on my dissertation, so I now have the option to sit or stand while working!  
I love the color too!
