Review on 🚗 2 Pack Car Cup Holder Expander Adapter with Adjustable Base - Versatile Cup Holder for 32 oz - 40 oz Bottles and Cups by Broderick Shetler

I highly recommend this product. I had serious doubts, but the base unscrews so you can fit it under your cup holder. I have an F150 and a Chrysler 300 and they both work great. It even fits in my lawn mower cup holder. I have a 32 ounce water bottle (large base) and it still has room for an even larger water bottle. It has flexible flaps inside the cup holder that also prevent your water bottle from sliding around in the cup holder.
