I didn't know these portable monitors existed until a few months ago. I wanted it as soon as I saw it. It was on sale a while ago so I pulled the trigger and I'm glad I did. This makes working on my laptop so much easier and more efficient as I can have two monitors like on my desktop. The biggest downside is that if I just plug the portable monitor into the laptop and not the wall outlet, the laptop's battery drains exponentially.
