works amazingly with my Dell XPS 15. Currently is connected to a widescreen 4k monitor (vertical), wireless keyboard and mouse, speakers AND headphones, laptop fan (only turns on when laptop is connected to Dock) two usbs and a external harddrive. Love how I dont even have to open my laptop for it to work, I could use everything thats connected and display it all on my external monitor. Also love the power button.
I've noticed when I connect a bluteooth device while watching a video, that there is about a minute of hiccups from the whole setup. Goes back to normal after though. Only thing I would change is the ability to choose which side to take the USB C connection from. Forced from the left side but I keep my laptop to the right. A little awkward for cable management.
