Call it a 4.5.  I really like this table and the fact it has wheels, making it much easier to maneuver.  Storage areas are also pretty generous given the size.  Material is pressboard, which is why it is so heavy, but the laminate finish seems sturdy enough.  Will see how it holds up.

I took my time in assembly so it took about 2 hours all together, and despite reading things three times, still managed some backwards placement so I ended taking things apart again to reposition.

Another reviewer indicated the glue containers (labelled as 5 on the bag), but they were never directly referenced in the instructions.  A pic was there but without the "part" reference I thought the instructions were just showing the dowel hole.  Even the parts list didn't actually indicate what was in the tubes; just indicated the part number.  The tubes were shaped in such a way that they weren't readily identifiable...the shape looked like they could have been actual parts.
