Excellent choice if your laptop power consumption is less than equals 130W
Can work up to 3 monitors !
Sometimes needs to disconnect from laptop and connect again to synchronize the monitors.
Is you laptop power consumption is over 130 W you need you laptop extra power :)

The only way to mount is 2 screw.
Not possible to mount using anchors (old boxes)
Finally and the most important.
Doesn't support 2 way....
