I got mine last week and have been playing with it for a bit. Here are my comments.
Mine works with Asmedia USB controller. But, only after I had updated to the latest Asmedia drivers.
Installation of vjoy for the infinite screen extension app was not that easy. For the first few times on installation it would hang at 50% when installing the vjoy component. A few reboots later the install was successful. Running Windows 10 btw.
Eye tracking does work in elite dangerous but it feels a lot different than head tracking. It works very well if you want to lock your gaze on a target but not as well if you want to scan something quickly. For example, I found it difficult to track a target, look at the radar, then find my target again.
You don't get a sense of orientation with eye tracking. If I am tracking an NPC, I don't get a sense of what direction my ship is facing and which direction I should move my stick. With head tracking, it is more intuitive as your head direction dictates which way you should pull the stick to bring the ship around.
I am 6'2", wear glasses and am using a 27" monitor. I had to add a small shim to the bottom of the mount to angle the tracker slightly higher.
I haven't made up my mind about eye tracking. It definitely works. I also got EDtracker a week before the eyeX so I've been busy experimenting with both.
