On BMW X6 I can not reach the middle of the front and the middle of the rear window, and sometimes it is necessary. I tried different catches, but everything is not very much. I saw this cheek and decided to try. Working surface in the form of fleecy synthetic fabric. Technological, of the two halves, located at an angle to each other. What this will give in practice-I do not know yet, but the quality of the details, their fit give hope that the thing will be useful.
