4.5 if possible, but here is the deal:

Assembly takes a LONG time.  They could definitely make this easier.  Additionally, the parts are pretty flimsy and feel cheap.  It looks nice, but all the cabinets and shelves are quite small.  OVerLl for the price I am pretty happy with it, but I know it won't last for a long time.  I will probably replace this within 2-3 years.
