Dock does what it's supposed to do, no issues. Screen and especially the Display Port on my Surface Pro 4 are dying, this allows me to basically turn it into a desktop again and expend it's life a bit until I decide on my next Surface device.
Microsoft Surface Dock
Received my dock after a long wait. Dock was in a back order due to a high demand because of an increase of home workers. I was kept informed and received the dock. Packaged well. I connected and it has performed as expected.
I use the dock at home and at the office. just sit down plug in one cable and i'm good. hopefully next version offers 3 monitors
