Gravity NS MS 03

This product does what it should and suits really well on my black micstand so when folded it is almost hidden from the camera. stable with papers on it and feels like high quality.

Incredibly configurable holder. Pretty stable(obviously depends on the stability of the stand itself). Can be tightened pretty well so it can bear a reasonable load. In my configuration, it takes a stick control book, a notepad, and 2 iPad minis - so far so good:)

Attached it to my drum rack behind the toms since I can't look to the side due to neck pain. Works well but it can still move around a bit so I'm not sure if you could put a heavy binder on it, but maybe I'm just not strong enough to tighten it properly.

the music stand is not attached to the clamp securely. It quickly began to spin

For me this is a top product well made at a reasonable price.
The unit packs up small for busking its brilliant , also Thomann is a great company to deal with reliable and caring about their customers, i recommend both the product and Thomann

Everything you expect form folding music stand.
Folds small, clamps easily and it is sturdy enough.
4 stars for quality because clamping mechanism is made of plastic, not much of a problem, but I am used to metal clamps.

It's very useful to have a music stand attached to a microphone stand, and this one is light and barely large enough to hold a 13" tablet and a vertical A4 sheet and still be fairly stable (I wouldn't dare to use that config outside even in light wind, however).
However, the two short bars (the top corner ones) are pretty loose, turn too easily, so they don't really add much to the stability.
