### ⭐⭐⭐⭐⭐ game changer
*by J***S on June 28, 2024*

i use this in my 90s 4x4 and 2018 4x4 i can fit a nalgen yeti what ever. TIP if it fits loose in your cup holder take a piece of duck tape. roll it like a cigar sticky side out and tape it to the cup holder where its sits in your factory cup holder and push down. its now locked in and will hold big cup full of ice and drink.

### ⭐⭐⭐⭐⭐ Works for my Stanley coffee mug
*by J***R on December 23, 2024*

I needed something to hold my 48 oz Stanley Coffee mug, and this is the perfect size for that.

### ⭐⭐⭐⭐ Nalgene bottle now fits in the cup holder.
*by M***N on August 14, 2024*

The cup holders in my vehicle are small and a Nalgene bottle will not fit. With this adapter I can now put my Nalgene bottle in the cup holder.
