Anyone who owns a smartphone knows that it can be very helpful in many situations. Whether as a navigation device, a shopping list, or simply for entertainment purposes – the possibilities for use are virtually limitless. The revolutionary Quad Lock mounting system makes using the smartphone even more practical and versatile. The main component of the Quad Lock is the case, which is attached to the smartphone. This serves both as a sturdy protective cover and as a counterpart for the various mounts. The cutouts for connectors and the camera are, as usual, present. The case is made of durable polycarbonate plastic, providing optimal protection. On the back, there is the passive part of the mounting device for the different mounts.
