With dimensions of 30.6 x 24.0 Haltebplatte of approx cm the stand from 15 inches for laptops is just right.
The outstanding feature is that the folded stand at just about 1 cm at the thickest point is so flat that it can hardly be undercut well. So that it can be taken without any problems in the notebook case.
The stability is surprisingly good given the delicate-looking design, pronounced weaknesses are not recognizable. Sharp edges with injury, there is not, of course, such a thin sheet is always in a sense, "sharp".
I use the stand, because I like to work on the go with an external keyboard and wants to bring the notebook display then to a comfortable working height. And for exactly this purpose the stand is optimal.
