First the speakers. They're of such terrible quality that you'll want to connect to external audio. The screen has a low resolution compared to other monitors in this price range. Low quality internal electronics. There is no reverse polarity protection on the 12V power input. Although it can accommodate your Raspberry Pi, it is not compatible with most coolers.

Followed the instructions to install the Raspberry Pi 4+ but couldn't get any sound out of the monitor. The system boots, Raspberian works, but there is no sound. Not from music files, not from games.

I bought it to use as a second screen for PC stats. It was easy to get up and walk right out of the box. It can be powered by USB power. It was exactly what I needed.

This is the second screen of this type I've bought, the first didn't last long. I have it running 24 hours a day, 7 days a week with minimal burn protection so we'll see how they hold up in a year or two, but after a few months no signs of burning and just works. My use case is likely a worst case torture test scenario, so I'll update this review over time.

Excellent goods. Bought to use with Raspberry Pi. The touch function is very responsive. Good sound quality. Robust construction. No complaints.

It was the best choice for me. Easy to transport, closed case with inputs etc. The touchscreen is worse than expected. Ideal for service, travel, etc. Use the Pie's dual output when you need a larger screen for gaming or movies.
