The first time I drove to work, I went through my usual routine which includes grabbing a can of soda for the ride. I was very disappointed to see that the cup holders were so large that the can was tilting and spilling all over my new car. I ended up holding my beverage all the way to work which is not only a driving hazard but the soda was warm and flat. I was just about to give up my morning beverages when my friend gave me a Drink Docker. It fits perfectly into the cars cup holders and now my cans and cups stay steady and the beverages stay cold for my commute. Thanks for this simple yet fantastic product!!
