They work wonderfully!! We were very disappointed with the substandard front seat cup holders on our 2009 Subaru Forester. They are deep and square, so cups sit in them too deep to comfortably pick up while driving unless we order a vente and the square shape results in cups that are jostled about during a drive, further resulting in coffee spurting/spilling out into the cup holders. The Drink Dockers fit perfectly into the front cup holders. They hold the cups a little higher so they’re easier to pick up for drinking while on the road, and keep them snug in the cup holder, so we haven’t seen any drips or spills.
