Traveling a lot for rental cars I tried several systems for my GPS in this one is a real pleasant surprise. Aerator to claw systems are not very stable and above almost impossible to remove. The suction systems are good but can impair vision requires the "big" a long cable car to go up the cigarette lighter. With this system we have a compact device, which adapts to different cup holders with an adjustable base by rotation, and the support distance / cigarette lighter is always short. However disadvantage GPS is placed relatively low this can be less secure than a GPS in the fields of view of the windshield.
