Review on Duex Portable Monitor Laptops Compatible 12.5", 1920X1080P, 60Hz, Attachable Laptop Monitor, Glossy Screen, DUEXLITEGREY, IPS by Brandon Woods

The magnets stick to your laptop with 4 small adhesive connectors. A day later the stickiness was gone and the whole thing fell off the laptop. I can still use it, but now it's smeared with putty and backed with highlighter. The screen doesn't stay straight either. Even if I didn't have to prop it up, I would still have to put a piece of paper on the guide to keep the screen level.
