Review on Gretutu Triple Portable Monitor Laptop USB 13", 1920X1080P, 60Hz, ‎Monitor2021, HD, IPS by Matthew Springer

Great product that exceeded my expectations. It has Full HD 1080p resolution, so it's great for secondary tasks or watching videos while working or using the main monitor. Put one side and squeeze a little to expand it until it reaches the size you want. The inside of the frame is protected by rubber so we don't damage our laptop monitor. I definitely recommend it!
