Review on Mobile Pixels Duex Plus 13.3'' Portable Monitor - Full HD IPS Display, Dual-Screen USB A/Type-C Powered Monitor, Adjustable Brightness, Anti-Glare, 1920X1080 Resolution by Tom Shapiro

This works wonders when you need a dual monitor! I like that it has magnets to attach to a laptop and the screen itself is big enough. You can control the brightness and it's really easy to connect and install. The only criticism is the magnets. After a while, they no longer stick to the laptop. Will probably have to buy more holding magnets or something.
