Easy installation is fast, easy to maintain and looks good, but ... A major disadvantage is the removable tray for the keyboard, it is just too short (can be easily replaced by a deeper board but) I support you up to the shelf board and for the track is not designed because it is very a thin aluminum is (small modification to the rails and even the supporting goes back :-)). Additional investment: Material: 25 | Time: 30 minutes Storage space is also given good and therefore a worthwhile purchase. As even some expensive desks can not compete with the functionality and design! Construction time was with me alone about 1 cozy hour. All in one: PERFECT!
