The official Samsung Galaxy S3 vehicle dock allows you to store your Galaxy S3 in your car in a number of different ways. The holder is designed so that it can be adjusted to suit you into a position most comfortable for you. The ECS-K200BEGSTD holder features a robust and smooth ball joint which allows you to easily position the S3 in optimal positions for both portrait and horizontal orientations so you can view it safely and legally when driving. The quality of the design and materials ensures that when the phone is in the holder, the joint does not move under the weight of the phone or when the car is in motion.
