The operation is simple and fast. Insert smartphone - press clamping jaws together - done. The device is released at the push of a button. The clamping jaws with integrated rubber pads guarantee a secure hold. The exchangeable support bars with different depths can be individually adapted to the smartphone so that the function of the operating elements on the device is not impaired. Thanks to the flexible ball joint, the holder can be tilted up and down, and rotated 360°. The flexible support arm with a length of 3.937 provides additional individual setting. An attractive metal base with non-slip rubber pads provides excellent stability.
