Simple mounting, somewhat inflexible for larger tablets

The bracket can be easily attached to a mic stand, even if it is meant for headrests in your car.
The build quality is ok and so better than I expected for a product in this price range.
The "bracket" are a little fragile, but holding the tablet firmly enough.
Unfortunately, I can my 8.9 "Kindle not vertically installed in the bracket, but it is too high or the holder too small.
To edgewise incorporate the tablet and only to fix the side, the holder are not stable enough and can not even notice.

After I now even had the Helterung on stage and in two samples in action, I have to say that I am completely satisfied.
To use the tablet horizontally, is clearly more practical than edgewise. Although upright may adjust the entire lead sheet on the screen, but is too small. So I only use it horizontally and the alleged restriction is not.
For the price, the holder is good and I would buy it again.
