Cup Keeper Adapter (2 Pk) expands Narrow Car Cup Holders from 2.5-3" up to 3.25" in Diameter to Hold Mugs, Convenience Store Cups, Water + Soda Bottles up to 3.25" Wide and 8-10" Tall (Gray)

Base is a little smaller than my cup holder but still pretty stable. I put a silicone wrist band around it now it fits snug. Thicker than I expected for the price

Good quality And helpful to holder my mug But it expensive
