I don't have a fancy car with adequate cup holders. And while I'm not prone to drinking or even carrying beverages in the car, there are times when I wish I had somewhere to put my fat guy jumbo chocolate shake on the way back from lunch.
I bought this little do-dad a couple years ago and never used it until today, so I thought I could offer a review.
As you can see it is very slanty. Had this been a soda, it probably would have spilled all over. It was pretty scary when driving a bit rough, but I never steadied it and it held pretty well although it moved about quite a bit. I won't bother posting the name and model as I'm sure there is something better out there.
What are y'all using?
