Is the EcoNour cup holder expander worth it?

At $9.99 at Walmart as of November 4, 2026, it is a cheap fix if your bottles don't fit your car's cup holders. It is plastic, so expect a basic fit rather than a custom one.

Will it hold a 40 oz Hydro Flask?

Yes. The mouth is 3.8 inches across and the brand lists 32 and 40 oz flasks, 40 oz 50/50 flasks and travel mugs as compatible. Bottles wider than 3.8 inches will not fit.

Does it fit my car's cup holder?

It fits cup holders wide enough for its 3.9-inch base and works in cars, SUVs, trucks and RVs. Very narrow or shallow cup holders may leave it loose.

Do I need tools to install it?

No. It drops into the existing cup holder with no tools or hardware. The U-shaped cutout on top lets handled mugs sit upright.

The best new price was $9.99 at Walmart as of November 4, 2026, with two stores listing it new. Small accessories like this rarely drop much below $10.

Its 3.8-inch mouth fits 32 and 40 oz flasks and travel mugs, and a U-shaped cutout on top leaves room for mug handles. It drops into most cup holders with no tools or hardware. At $9.99 at Walmart as of November 4, 2026, it sits at the low end of its recent price range, with only two stores listing it new.
