One thing to keep in mind when working with a Macbook Pro (and other laptops) is that you won't get the best speeds from an adapter if something else is plugged in the same page. So if you use 2 4k monitors, your ethernet speed will not exceed 300Mbps. I initially left a bad review because I couldn't get over 300Mbps with this one. However, when I unplug one of my 4k monitors, I can get close to the maximum.
