Review on ELECROW RC050S: 5" Capacitive Touchscreen Raspberry Monitor - Portable & High Resolution (800X480P) by Aaron Surabhi

I have many small Raspberry Pi screens and this one is probably the best I have. It has good image quality and I love how you can wirelessly attach the Pi to the back of the Pi. It's easy to install and works out of the box with my Raspberry Pi 3b+, the latest Pi OS and Retropie. The touchscreen is very responsive, which is a big plus when there's a speaker for audio, and it sounds really good for a small speaker. You have to change the setting to get HDMI to work via raspi-config for the sound to work, but I played Galaga on a Retropie when I first hooked everything up and it was excellent.
