This docking station works well with my Surface 3 AT&T model. It quickly allows me to bring it in the house after being on the road and be up and running in full desktop mode in seconds. It just as quickly disconnects to allow me to hit the road again later. If you use your Surface at a desk I highly recommend this docking station. It has all the connections you need (more USB would be nice, but a hub works fine too) and also includes a separate AC adapter so you don't have to connect your travel charger when you get home. Nothing worse than climbing under your desk every time you want to use your Surface at home. So with this I don't have to and it's great! I should note I was able to pick it up on sale which made it a great value. It would still be nice at full price, but everyone loves a deal.
