It looks to be an improvement on the yellow ones but its obviously still not aimed at the mechanics market, more general tool storage with lots of room for power and cordless tools.
I like that the top box now has a full width drawer, along with the one in the bottom box, giving you two of the most useful sized ones.
The deep bottom drawers do wast space if you don't need to house bulky items but who would want shallow ones down that low anyway, since they have dual runners it may be possible to change each out for a pair if you could get spares and the dimensions worked out, they may even make an alternative version at some point.
They could do with making a mid box for it with about 4 or 5 shallow drawers for smaller items, the stack wouldn't be too high with another 12" or so added in.
