Been using this furniture for about a month now.
My spare bedroom is multi-purposed, so I set up the unit as an L shaped desk and a stand alone desk.
I use the collaboration desk for my primary desk, a purpose it excels at due to the extra depth of the desktop.
With a 28" wide-format monitor and the keyboard tray attached, there is plenty of room for manuals, binders and legal pads.
The L shaped desk serves as the desk for my personal computer. and I use the surface under the hutch to house a color laser printer, and use the hutch for typical office supply storage.
Very pleased with the way it works for me, but there are two pretty big cons that detract from this being an excellent purchase:
1). The drawers under the hutch are complete crap, with only about 3" of storage height in the top two.
2). The drawers also do not line up, and make it obvious that this isn't a quality product.
The doors on the hutch are similar, but at least they can be adjusted, and made to hang in a fairly uniform manner.
I would recommend buying the unit especially if you can avoid getting the filing cabinet.
The saving grace of this system is the desk surface, which is very good.
