I'm a light and filigree holder for my 7 inch Tablet searched, so I can use it as a navigation device in the car it every now and then. All the other holder had me all too bulky and heavy, the Defender holder is different. It is perfect for use as needed. Quickly taken out of the glove compartment and installed Super. I lock it always that easy rests the lower area on the dashboard, so that everything is stable because otherwise the vibrations transmitted to the car by the holder arm, but that is at each holder that. For the price of the Defender is always unbeatable.
However, if a holder of searches is constantly installed in the vehicle, should rather think about one of the bigger "grippers" holder because that are more stable in the long run, but of course cost more. For rapid deployment in between the Defender, however perfect.
