The Kenu Airframe is super processed and has a metal core, plastic coating and anti-slip rubber coating at the relevant points, ie at the mounting cross and on the side parts holding the smartphone. It can be pulled apart and can be customized to different mobile widths. The relatively high train ensures that no cell phone slips. This insertion and again removing the smartphone with one hand is a bit fiddly, but doable. The attachment with the rubber cross the ventilation grille in the works Ford Focus quite well, where you have to note that the weight of the smartphone takes the grille downwards. This may in unfavorable mounting of smartphones mean that the display is greatly inclined, making it difficult to use. However, this can be prevented by varying the hold on the smartphone in my case.
