Can be assembled very difficult

Finally, I made it with a hammer, had this feature but you risk damaging the bracket. You have to push the plate with the four grippers so far up or hammering that the lower edge of the holes is visible to about 1 mm.

I suspect that half of all buyers returned by the holder to be defective. Something better has not earned the manufacturer.

Another problem is that the vertical angle of the bracket can not be set in relation to the ventilation grille. The holder can only be good to vent, blow the approximately 30 ° to 40 ° diagonally upwards, depending on the depth of the slats. For vertical grilles which part depends rather unfortunate downward. In most cars, the two support legs sit on its edge and leave in the long run may dents or scratches on the dashboard. One can in such cases, at most by remedies that you yourself tinkering a spacer, to be glued under the support legs. But this can not be the purpose of such purchase.

It is good that the slats clamp can rotate. However, it is a little stiff, so that some buyers may not come up with the idea to turn it. Rotating it by grasping the spring-loaded plastic slide and rotate with some force. This fits the holder, if any, on Ventilation, whose fins are not horizontally.

All in all can not recommend this device.
