Only stable stationary state

Plus points:
The stand is very good if you want to use the iPad as a TV and simple it so wants to put on the table. Rubber elements keep the Ipad a well on the tripod firmly and secondly the tripod on the table. A friend of mine has used it as a picture stand, it convenient hiding behind the image and brings it great to bear.
But:
It makes a very shaky impression if you build it or composed. I'm curious how long it keeps. The joints raced hard, and the feet are not fixed, so quickly slip down out (but what is not a problem as long as one does not want to move together with the iPad the tripod).
Conclusion:
I know of no alternative, and me, the iPad is too expensive (etc. books) to provide it with makeshift vertically, thus restricted buy recommendation
