Well made, looks robust and relatively cheap. Unfortunately I found myself reconsidering my choice because:
Only one handle per side means that it's supposed to be carried by one person. If so, it should not exceed 25 Kg overall.
If so, then you only have 25-11,5=13,5 kg of equipment available in 10U (1,35Kg/U). A piece of equipment that weighs 1,35Kg/U is never going to be 45cm deep, unless it's an empty tray.
Make your calculations before buying or you'll find yourself either with a half-empty box or with a heavy an unbalanced rack that is very uncomfortable to move.
