Workbench Black : Does what it is supposed to do

I have the desk for about a week now and used it quite a lot for the time that I have it. First of all it was not too easy, not to hard to build it. Took me quite a lot of time (more than 2 hours) since the one piece of paper manual has only 6 small pictures as instructions but then again I did it alone and I don't have much experience about setting up desks so someone who has done it before or has some help might do it easier and faster. The desk looks amazing and has a lot of space for gear. The drawer doesn't seem too bad but I haven't used anything heavy since my keystation pro 88 is extremely big and doesn't fit there but it seems that it can easily hold any 61 keys synth without any problem. The rotating shelves for the speakers are great. One thing that troubled me quite a lot was how to mount my gear on the racks. Once you build the desk and place the upper shelf there is no way to screw anything inside the racks because the screws simply dont fit in the racks. You have to place the screws in the racks before the upper shelf is in place in order to mount your gear. That's not a problem if you have everything but if you are like me and always improving your gear that means that every time you buy something new you have to get your monitor and speakers down, unscrew the upper shelf to take it out, mount your gear and then put them all up again. That is the only con i could find in the desk since in everything else (and in looks) it is amazing.
