The overall size of this desk is great, I have enough space for a full keyboard, oversized mouse pad, speakers, microphone, laptop, picture frame and some extra for writing/working. The standing portion of the desk works great, it's not necessarily quiet but it isn't loud enough to be a nuisance. 

My one gripe with the desk is because the panels are separated, there is a tiny gap/difference in height between the two panels. So, if I run my mouse over the gap it can be noticeable. The only time this really matters is when I'm gaming though and even then, I just move my mouse pad back a little bit.
