Review on Dual Car DVD Player with Headrest Mount - ARAFUNA Two Headrest DVD Player with 2 Headphones, 1080P Video Support, HDMI Input, AV in/Out, AC Adapter, Car Charger, RCA & AV Cable Included (10.1" x 2) by Joseph Stone

I purchased this item specifically for HDMI and dual screen connectivity. We had a 30 day trip. We installed it before the trip but didn't really use it until we went on a trip. Unfortunately the features I bought it for didn't work and I missed the return window because we were traveling. I bought HDMI cables for iPhone and One Plus phone so we can connect all my teens phones so they can watch what they want. downloaded so they could watch something together. Connecting the iPhone required some sort of app that we were never able to download and run. One Plus connected but nothing played on screen. We were able to connect my Samsung S21 but it only played on one screen. The ability to work with two screens did not work. I've spent hours searching how it works but to no avail. Since none of the differentiators work and it's just a dual screen DVD player, it's very expensive. I already have an $80 device that works just as well. The return window was only 30 days so I wasn't able to return it when we returned from our trip.
