The sucker keeps very well, in 20 days I did not have him install again. However, it needs a relatively flat and structure-free surface such as windshield. On the dashboard of the Fiat 500, I could not fix it, but it was too crooked either or structured. But if he keeps, then it stops right!
More joy brought me the hinges. Everything really made robust, you need have no fear that the tightening something breaks. In addition to positive connection and positive locking is used (Pip). Result: not a squeak or wobble when driving on the premises or little flat road. Excellent!
I can not think of better support for my equipment. A big thank you to the developers and producers!
