The tool itself is fine, but it is not tip top adapted to 107 / C1: indeed, the central ventilation grid is not deep enough, and "spheres" side ventilaiton (proprio 107 / C1 include) rotate under the weight of Kenu. Well, my technique was to put the Kenu very bottom of the left Sphere, like that, it takes the sphere and can no more turn. By cons, it is not tip top as visibility of GPS, but a priori correct (I have a long journey this weekend where I will use, I will correct this com 'if it proves not viable). Anyway, the tool is finished.
