The recesses are all available, so that the camera is available and especially the speaker is exposed and the sound can propagate properly.
The bracket can be rotated and (almost) infinitely firmly locked. (If it is exactly in the gap of the gear flanks, just tighten a little back and herd back and then really fix).
The suction power is very good and has so far fallen on me.
Unfortunately, this does not stop on my dashboard so that I "only" can be attached to the disk (therefore not suitable for every dashboard ... But if it is not rough, it should work and the holder may complete and clean the required vacuum manufacture)
In addition, the engagement and disengagement even requires a little power (to press down the nose). This guarantees but a firm hold and ensures against accidental fall out.
For the price absolutely OK and recommendable. The build quality is also good!
