When the rack is assembled, it is very good, that's why the 5 stars.
But…
The assembly is a hassle. There was a tool included that was useless (see the professionally filmed video I uploaded). Have your own tools ready. You will need a large Philips screwdriver, a 13mm wrench, and I think a 10mm one, and patience. Take your time, assembly is not difficult, it just takes time to put in the bolts. The biggest problem I faced was with the wheels… the nuts that go in gave me a really hard time, put 2 washers on each nut and slowly, with music and some swearing, you'll manage. Also, the bolts are black and not the color of the rack (grey), as is the cable management, which is also black
