Excellent secondary display for laptops

This portable monitor clips relatively easily on the back of a laptop. I was quite surprised at how clear the text is on the 12" displays. 

It works great for reading spreadsheets and word documents as a secondary display, using the 15.6" widescreen display of the laptop as a primary. 

The interfaces of the two displays are apparently able to be daisy-chained, however, I was unable to test this function since they did not include a long enough USB-C cable.

I am overall impressed with this display for the listed price.
