    Works perfect with the note 10. I use it for both DeX and screen mirroring. No issues. Using the samsung charger it passes through pd charging as expected and 4k video.

    Eventhough it is not the OEM Samsung DeX adapter, it serves as such for the price. Above all, it is great for mobile presentations as it is seamlessly connecting to the projector.
