Review on ASUS ZenScreen MB166C: 15.6" Portable Monitor with Anti Glare Screen, Flicker-Free & Blue Light Filter - Ideal for Productivity and Entertainment by Paulo Hoelzle

When it works, it works very well. It doesn't like cold and will sometimes refuse to turn on or stay on when it's a little cold (like in a heated room but sitting against an outside wall). It also refuses to turn on (e.g. to check battery levels) when not connected to anything, which was confusing at first but is now just frustrating.
