Stable for tablet and ebook reader

As an already wrote before me, simply change times is not. The wing nuts must be solved, all aligned and tightened. In addition to the rods are still tightening systems which can be solved to swing sideways. Then you have to mentally just get everything on the row in order to understand: "that needs to be turned there so I can turn and then because it then can do so". But it works. The system is stable after tightening.
You have to plan something that when it just right it builds naturally sags slightly downwards. So you have to fix a ratchet stop it earlier.

I currently have the system on the sofa hanging on shelf and clamp in there my Kindle. Then I need only lie idle and to turn the page up and down.
The Kindle keeps it upright as in landscape mode. My ASUS 8 "tablet is only cross in the mount. But what is a problem, because the holder is also rotatable. Et Voila, portrait mode again.
It is sufficiently stable that the system I entrust my tablet to keep it over the bath.

Installation is also done very quickly and easily.

All in all top!
