Not sure about anyone else, but my cup holder divider would slip out when lifting my drink out. This is super annoying. I bought a new divider and it's no better. So I tried to fix it myself. I needed something to make the grooves a little thicker, or a little gripper so they wouldn't slide so easily. My solution was to insert a thin layer of super glue into each groove. After letting it dry I roughened it up a bit with a knife. The result? Much stickier / grippier cup holder divider.
Hope that helps anyone else out there with the same problem.
