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.

Works well, looks stupid with the logo display
This fits well in the vent frame and I am still able to close my vent. I really like the mount cause it solves a huge problem of where to put my phone securely... but I also hate it as well, because of the ugly logo on the face of it. "Batdiary"? Seriously? If I keep it I will look for a way to get rid of (or cover up) the extremely unattractive logo they selected. It makes it (and my trucks interior) look loke something for a child. I give it 5 stars because it deserves better than the 3.9 it had at the time of posting this. But for the love of everything clean and classy but still needing a mount, get rid of the bat logo!
