This particular shelving unit is a good product for the money it costs. The only tool a person will need for assembly is a plastic-headed hammer, for a better fit. It is as simple as a child’s Lego. I emphasize that it only requires one person, with normal brain function. However, if you considered Lego constructions difficult, then you will certainly struggle, but the issue is not the shelving unit, but that you can’t even handle the very simple things.

Overall, it is an honest purchase... I didn't like that the whole construction falls apart very easily until you assemble and set it up... once it is secured and objects are placed on the shelves, it becomes a perfect tool and is indeed what I needed...

The black color and the external coating make it more special as they give the impression of quality construction. This feeling is not far from reality as it is one of the best value for money options. 4 stars and not 5 because its connections fit very easily, they do not tighten enough, resulting in it moving if it is not screwed to the wall.

Simple but good and it holds quite a bit of weight, now I don't know if the weight they say is accurate. If you screw it to the wall it doesn't move at all

I expected it to be more sturdy, that's why I gave it 4 stars. Later, when I load it with heavy items, I will see how reliable it is in terms of durability.

This is what the shelving unit has been transformed into.
So, what I have done: I assembled the shelving unit with the second shelf from the bottom at a classic table height of 74-76 cm.
Then, I bought an olive wood board, two centimeters thick (which I treated with varnish and wax).
Next, I bought two pipe-table legs to support the table on one side, and on the other side I placed it on the shelf (I also put a weight like a microwave and a coffee maker so the wood doesn't move and stays stable, but even on its own it doesn't have room to move because it's cut to fit exactly within the shelving frame).
Finally, to give it an extra kitchen furniture look, I took plywood and screwed it to the sides.
If anyone has any questions, I can provide more details.
