Cart Tek's rubberized multi-media-holder will securely grip your device such as a smartphone. The rubber allows for the smartphone to be cushioned when going over humps and bumps and jostles, without damaging the smartphone. To install, simply wrap the band around your handle, and slide through the mount. Make sure the band is looped over the little locking bump, and you're all set!
