Don't own one. What I saw in them is how deep the drawers are (57cm) and the load capacity, and the possibility to order the drawer configuration I wanted. And I love boxes with few BIG drawers so I don't have to spend the day shifting between them looking for tools. (think all 120cm wide x 57cm deep drawers from top to bottom)
These are industrial cabinets. Sure don't look like junk to me - take a look at this video and judge for yourself:
IMHO you get a lot for your money in these judging by the prices in the online store. And from the description they are in different league than most automotive oriented toolboxes. (material thickness, 200 kg ball bearing sliders etc..)
