I ordered this support to be used on our camper trips to make videos with action cameras (I have more than one).
The suction cup does its job well, thanks to its mechanism it pulls well, adheres and remains stable, obviously this also depends a lot on the type of surface to which we fix it, for safety I fixed it to the glass which is the smoothest surface.
Despite being made of notched plastic, the joint at the base, which adjusts the inclination, is very precise and stable once stopped, and so is the upper one, which works with the classic sphere and also adjusts the inclination to 180°. It is also possible to rotate on the axis, always in the upper part.
The supplied accessories allow you to fix the cam both with a screw head and with the usual 3 vs 2 interlocking support with a side screw, and then there is a specific support for Insta 360.
At the moment the product works well, even if the adjustment of the upper part is a bit cumbersome.
I'm a bit worried about the part of the plastic notch due to the inclination of the base, which will certainly be subject to wear, but I don't want to be prevented in this regard, we'll see how successful it will be over time.
