Hi you may find the genuine KIA OEM work fine.
I have them on both my 2018 MY Venga and my 2021 MY Sportage.
The later KIA ones for the Venga are shaped to allow the mirror to fully close towards the door.
The earlier KIA ones for the Venga did not and the mirrors hit the deflector whilst trying to close.
I appreciate that the Heko ones will be cheaper than the KIA OEM.
