Looks and works great!
Color: for Kia Carnival 2022-2024
The negative reviews are unfortunate, as I had zero issues with the 2 I bought. Fits the 2024 Kia Carnival SE Prestiges perfectly.

Holds the phone very securely
A little on the expensive side but it really holds the phone well. Much better than the vent clamp I was using.
