Bests & Worsts Reviews from Amazon

It doesn't work the way it's supposed to, and I had to jump through hoops for a week to get it to work at all. I'm trying to use this with my Dell XPS 15 9560 running Windows 10 Professional. I updated all the drivers, went out and bought several extra cables/adapters to try to get it to work in different ways, and even let Dell take control of my computer remotely at one point. None of the issues actually got fixed. Here are the problems I'm still experiencing: - Won't output 4K at 60hz at all, much less on multiple monitors. I've tried both HDMI and the DisplayPort. Since the main reason I bought the hub was to output 4K at 60hz, this was pretty devastating. - Attached USB keyboard and mouse are not recognized at startup so every time I turn the computer on--or wake it up from sleep--I have to open the laptop and log in using the laptop keyboard and touchpad. - Every time turn the computer on, the speakers I attached through the hub (3.5mm jack) go crazy, popping and spitting, and then when I log in, I get ten to twenty "Device connected / Device disconnected" notification noises. - Didn't recognize my attached game controller, which works fine when I plug it into one of the USB ports directly on the XPS. I tried to look past its flaws, but just now when it wouldn't even recognize my attached game controller, I decided I'd had enough. If I'm going to buy a glorified USB hub for $250, I don't think I'm asking too much if I just want it to work as advertised. I'm going to seek a refund.
