I want to like this docking station, but I don't trust it. It began flickering my screen after about three months of use and has progressively gotten worse. I've tried multiple HDMI cables, and I continue to get a randomly flickering screen. It also doesn't allow my computer to go to sleep—unless I manually lock my screen.
Don't even think about touching it, bumping your desk too hard, or even sneezing near it because it'll just turn off, at worst, and flicker the screen, at best. The power cable is plugged all the way (on both ends) and tight.
I can't rely on my external hard drives staying mounted, either and I've resorted to plugging them in directly to the MacBook. Kind of defeats the purpose of all those super-fast USB ports.
Another issue is when you wake the computer with an external mouse (Bluetooth, not plugged in). My keyboard is plugged into the dock and takes a couple of key presses to begin registering keystrokes in the login input. The third key press causes the dock to freeze and requires that I physically reset it with the power button.
And finally, I occasionally get the "USB Accessories Disabled" error on my Mac when I restart it. So I then unplug it and plug it back in.
I've tried this with multiple MacBooks, and they all experience the same issues. Even the sleep issue (it's not system settings). It never moves; I only occasionally plug things in and out of it. This leads me to believe there's something wrong with a circuit board but I purchased it refurbished (from AnkerDirect) and their warranty period is only three months. It has lasted me 11 months and I'm looking for something to replace it.
