Relatively simple but it seems good, I haven't made significant use of it. There is a large space at the bottom part.

The lid stands upright just fine if you put screws/nuts/nails etc. in the yellow compartments and the whole lid gains weight. Of course, the quality of the yellow compartments is not particularly good; there is a chance they will pop open because of the weight and scatter all the screws on the floor. Since I bought the toolbox for personal use (rarely) and not for work, I put masking tape on the compartments so they wouldn’t open by accident. Inside, the space is satisfactory. However, a drill doesn’t fit, neither lying down nor upright, only at an angle.
edit: It also lost its alignment; it doesn’t sit properly in the grooves when closing. It’s annoying because if the lid doesn’t close properly on one side even by 1 cm, you can’t latch it.

It seems to be a quite high-quality construction with a lot of space.
The only drawback I have found so far is that its lid cannot be tilted to stay open (see photo). You have to keep lifting it up and down – otherwise, it falls by itself. Maybe it will loosen up over time.
