This mount is a very heavy duty and won’t slide around. It just sits up on your dash – it has a non-slip bottom grip and is heavily weighted to prevent it from sliding around or falling. Just slide your handheld into the clip on the mount and you are ready to go. The mount is adjustable and can be moved and swiveled in whichever direction you want! You can also remove the window mount part to be used on the window as well.
