Sorry for the late feedback. I must say I love the Drink Docker! I have a 2006 Toyota Rav4 and have had the same problem with the cup holder not doing it’s job of holding drinks securely. Whenever I would turn a corner or intersection I would have to hold on to my drink because it would tip. The Drink Docker fixed that. I ordered a large one but when I put a large drink in it it would come out together with the drink. I used the rubber with the adhesive and now the Drink Docker fits snuggly in place. Thank you so much for your wonderful product!
