This dock allows you to connect to multiple peripherals. You can connect a much larger monitor , a printer, powerful speakers, a hard drive or a flash, a mouse of course, a keyboard and the occasional CD installation programs. All with ONE connection only, to the battery charger port. This prevents wear to the tablet ports, and makes connecting all these a simple one step. You can connect 2 monitors, and you can lock the dock using a laptop cord lock, as shown in the pic.

I bought this to hook my surface to two independent monitors. It is PERFECT! It is small so doesn't take up any room. I also charge my phone in it and the usb for my wireless mouse. It is AWESOME!!!!

I've read various reviews about this working half the time. At first when I connected 2 monitors, half the time only one of them would work and then I'd go through the whole restart thing to try and get them to work. Eventually I found that in the display settings that one of the monitors was just turned "off" instead of extended or mirrored. I don't know what made it default to this setting after the initial set up but after that things are going smoothly. The ports are super useful and I do wish there was maybe one or two more extra usb ports in there. Long story short, if you're a surface user like me and prefer a desktop type of experience, this is a definite recommendation

I purchased the microsoft surface dock to connect my surface to use when home on bigger monitors and it works great! I purchased two monitors to use side by side to be able to have multiple windows open. It has worked great so far because the dock charges and connects my surface without a problem. You will need to buy specific HDMI cables that connect to the dock and to the monitors separately. Great buy!

The Microsoft Surface Dock is perfect for my laptop. No more turning you laptop over and over to see if it has the plug ins you need. Plug in the internet, a camera with sound, a keypad, more memory to store pictures and data, plus MORE... Comes in any color as long as you pick Black!
