Review on Bigasuo Portable Monitor B-158: High Dynamic Range 15.6" Computer Display by David Toliver

I use it as an additional monitor. It's the same size as my laptop, it's bright and colorful, and best of all, it has a built-in battery so you don't have to keep plugging it in. There aren't many spots in the laptop. I can watch YouTube while working in Excel or I can have two Excel Maxium windows so I can easily compare them. This is good help.
