Just wrote the comment to point out that these are in fact not MINI bricks, as the title suggests, but diamond bricks. They're super tiny.
Also, the parts are sorted in bags, but not by building steps. Basically you need to rip open almost everything on the first page already and parts are scattered over all the bags. Half of the time building you will spend searching for the parts.
That kind of ruins the experience a little. But at that price point, maybe one should not expect too much.
The end result looks great though. But definitely my first and last diamond bricks experience.
