Review on DUEX Portable Kickstand: Lightweight, Adjustable Brightness, 12.5" IPS Laptop Monitor - Second Screen, USB Connectivity, 1920X1080P, 60Hz by Murray Novikov

If you are using this monitor via USB-A, I would not recommend buying it. I noticed that connecting USB-A is very slow, my Mac doesn't recognize it 3 times out of 4. I have to disconnect and reconnect it several times before it registers. Sometimes I wake up my Mac and see that the system thinks multiple copies of this monitor are connected to it, a problem I've never experienced with other USB monitors. The trigger mechanism is weak. When fully extended, it sags. I sent a message to customer support about my issues and never received a reply which always makes me suspicious of working with the company again.
