😀 THIS!!! I tested the large expanding cup holder adaptor that I posted last week and it WORKS so much better than I thought it would!! The base expands in the existing (smaller) cup holder and my 40oz Stanley was snug and didn't tip through multiple short stops and 3 roundabouts 🤣. Tried it with a 30 oz as well AND a tall Starbucks coffee. This is a keeper for anyone with a larger cup size that doesn't fit in their car's holder!! LTKtravel LTKunder50 LTKFind
