The K&F Concept magnetic camera mount for action cams, system cameras and cell phones comes with brief German information from K&F and a bracket including a knurled screw for attaching action cams, etc.
The bracket consists of a lower mounting part including a ball head joint, which are made entirely of metal. The magnetic foot is covered with rubber so that you do not scratch the surface of the object to which you attach the holder.
The ball head is equipped with a mounting plate (made of plastic) for cameras including a ¼ inch screw, which can also be unlocked and set vertically.
The ball head can also be swiveled and rotated very easily and fixed/released quickly with the knurled screw.
An attached action cam or a mobile phone with a separate mobile phone holder holds perfectly with the magnetic base.
You have to try out heavier system cameras yourself. K&F says that you can't hold more than 3kg with dme magnets.
We would therefore just not use such heavy cameras, as a lens also weighs and the weight is increased by any leverage that may occur.
Overall, however, this magnetic holder works very well, is very high-quality and robust and is also very practical. Recommended for this price!
