DEEPTER HDMI 2.0 Switcher RCA to HDMI Converter

I am selling this because I have replaced my car and it is no longer needed.
This is a set for switching between two devices to display on one monitor.
In my case, I used it as a switcher to display my smartphone screen (mirroring) separately on the rear seat monitor (same image as the front).

There are no major scratches or dirt, but please refrain from purchasing if you are concerned as this is a used item. Please judge the condition from the photos.

I am not very knowledgeable about this, so I may not be able to answer detailed questions. Therefore, please purchase if you can judge from the photos.
