Review on 📺 Eonon HD Digital Multimedia Monitor - 2021 10.1 Inch Super-Thin Car Headrest DVD Player with HDMI, USB, and Remote Control by Jon Lewis

I hate to give a bad review (faults happen). This device had a good assembly system and the user interface (controls) was great. BUT it didn't read an installed USB or SD card (the screen flashes on and off). I've tried all formats and several different 2.0 and 3.0 USB sticks. The hard drive worked fine. If I had time to replace the block I would try a different one. but the next day I wanted to travel. So it had to be returned. Thank you Amazon for the hassle-free return! PS I still think Eonon is a great company, they have good products and a lot of custom car stereos. I just got a bad block.
