I really like this metal laptop cart.  I could not find a metal laptop cart any where whether online or in stores. I use the cup holder to put pencils and pen, including my remote control for the TV.  The cup holder floats with the tilt of the table which is great design!!!  It is very easy to assemble, with easy instructions.  It is balanced.  I use it for my 17" laptop when sitting at the sofa or recliner.  I can put a mouse pad next to it.   The table is not too long nor too short for me.  I have an area carpet, and it rolls well.  The frame and table is made of metal.  The wheels, and hardware adjusting the height and tilt of the table is made of plastic.  The plastic hardware seems pretty heavy duty.
