I'm not sure mine is the same brand, but I definitely like the one I have. There is a knob to lock the mount in the CD player. There is another on the back to tighten the holder for horizontal and vertical position. I have to tighten this from time to time otherwise the phone tends to tip forward or wont stay vertical. Its been a great mount for me since I don't have a flat surface in my car other than the windshield.
