Only lasted a couple of weeks.
Model: 2014-2018 Forte
Was nice but after the first day, it would start to loosen and my phone would slide down. After a couple of weeks, it fell off from the car completely. It was a birthday gift so pretty disappointed.

Will not stay attached
Model: 2014-2018 Forte
I used rubbing alcohol to help it say attached. Unfortunately would not stay attached so useless. I thought of getting Velcro or some other type of product to secure it, but why should I have to work at getting it to work? I was never able to see how my phone would work as it never stayed attached

Doesn't fit 2022 forte
Model: 2019-2024 Forte
Didn't fit my 2022 kia forte. Had to cut the top of the bracket off so it could snap into place. With a little cutting and grinding I made it work.
