In the upright position, when you have the tablet due to the fact that it collects the lid from the inside out, it has a velvety lining that collects any dust resulting in it going and sitting on the screen!
In the flat position with the lid, if you try to move it a little, it simply falls off. Otherwise, it is a good construction with good materials.

I recommend it if you frequently move around and want the tablet to be secure. If not, it may not be a good choice due to its weight.
