Review on ArtJ4U Car Coasters: Durable Silicone Cup Holder Coasters for Any Vehicle (4 Pack) by Phil Prater

Fits my Hyundai Sonata console and 2 friends I gave as gifts that also fit perfectly on Toyota Camry. They help keep the cup holders clean and can be easily removed for cleaning if needed. They do exactly what I was looking for. I had an issue with them that prevented me from giving them a perfect rating: They fit too perfectly in the base of my insulated water cups and are usually vacuum welded to the cup when I put it in my cup holder. If I don't notice and take it off before leaving the car, it will fall off when the vacuum is broken. I used to notice and pick it up, but I've already lost one when I didn't notice. In order not to lose the leftover one, I cut the cork to fit in and prevent the car coasters from sticking to the bottom of the cup. So far, so good!
