When I got the part in the hand I was very pleasantly surprised: This is really high-quality plastic with proper thickness and proper screws in it, no Billigkram the already falling apart after a short time! When plugging together then I go myself somewhat surprised how easily the parts apart again, but the same was the Enlightenment: One must only "right way up" plug together so that it can also neatly into place, then it holds also true that it is only with effort get apart again. The holder can be in steps of 30 ° turn and engaged in these positions, so that it can be mounted in many different positions that fit the Garmin I can only describe with 100%. The tip with the screw from the other review can save you need, there is no design flaw but a user error.
