I chose this specific case because from the photos it seemed to fully cover the tablet, which is true. The access to the buttons is excellent, the fit is very good and it is not obstructed by the protective glass I have placed on the screen. Another positive aspect is the transparency on the back, which I find aesthetically pleasing as I did not pay 1,500€ to see the case. In addition, the black color does not easily get dirty and the pencil stays in place. I have tried it with both the original and another brand's pencil and the result is the same. For me, it is a great value for the money and I recommend it.

Update 13/10
After a considerable amount of time using it, considering I have a cat, it has scratched on the outside but without any internal damage. I have accidentally dropped it twice from the height of the desk (with a heavy heart) and I have not noticed any visible damage. However, it collects a lot of hair and dust inside the gaps around the pen and requires cleaning every day. Also, when I use the original pen, it constantly charges and drains the battery faster, so I have to keep it separate or constantly charge it, which negates the whole feature of having the pen always on the tablet. For this reason, minus one star.
