According to the brochure:

The stylishly designed Vogel's tablet holder fits all tablets from
7-13 inches in length (including iPad Pro) with a thickness of 0.2-
0.5 inches (0.5-1.3 cm).
Max. Weight load (kg) 2

So if it doesn't work, someone at Vogels has taken the cake.

We use the thing for a 9" tablet.
The part works very well with it.
But compared to the Pro, it's in a different weight category.

It won't hold, it's too heavy.
