I chose an old flagship at 75% off its value rather than a new mid-range model: the materials are of better quality, the camera is of better quality, the charging speed is much better, and there are lots of little details that mean that even 2 years after its release the Xiaomi 11T Pro is far from being outdated.
The parcel arrived very quickly from the Baltic States, around 2-3 days max.
As for the grade, I can't see any difference between "very good" and "average": there are no micro-scratches: it looks like the glass and screen are brand new.
For future purchases I'll take the cheapest grade.
In any case, the screen and back are protected and hidden by a shell, so it doesn't matter what the initial cosmetic state is.
