This cart was challenging to build...I would recommend adding the Installation agreement to your order.  The biscuits to cover screw holes are very hard and resist mounting.  The under drawer space was billed as 18" which was the driving force for me to purchase this cart...it is closer to 16"--a strategic problem for my storage needs.  The lower door is reluctant to contact the magnet close and comes loose very easily.  The castors are excellent and fit and finish of the pieces is quality.
