This is a useful tool if you have a waterbottle that does not fit in a standard car up holder. This adapter while designed for the Yeti 46oz bottle, can fit many brands water bottles. It also allows you to continue to use the standard size of your cup holder for standard size bottles or cans. You can also use it to hold change if you do not need the standard cup holder.
I hope you enjoy it and at helps alievate a pain point with an easy fix.
