The rubber grip inside actually holds my bottle tight, no more sliding around on turns. Even on bumpy roads, it stays secure in the cup holder now.

Finally, my big bottle doesn't tip over while driving—the expander grips it snugly without sliding around.

The Car Caddy keeps my larger Cirkul bottle snug and upright in my car's cup holder. Easy to install and doesn't wobble even on bumpy roads.
