well, finally got round to installing eye tracking and needless to say i am in same boat as many here. ir leds dont light up that i can see. eye tracking shows up in device manager as drolon p1 , tried connecting it with each headset usb. calibration shows two green dots for a second and vanishes. Many thanks to XabbuSwe for trying to troubleshoot it for me on discord.
What a mess.
If the green ball disappears inside the two squares while drolon p1 is displayed, another unrelated program is using drolon p1.
Find it and turn it off.
I connected the drolon p1 as a video player as a test and it showed such symptoms.
If this is resolved, it will work as well as the video I recorded.
Eye tracking is a mess, butā¦
apparently if that is happening the leds light up, my leds are not lighting up.
some interesting info, on xabbus suggestion i replicated the above āproblemā by getting discord to use the ET as its camera. This resulted in no green preview video as would be expected for him. additionally the right side eye tracker light ring lit up, the left did not. (this is first time any of the tracking ledās have activated. ) The tracking ring would not turn off even when discord camera use was disabled. The lit tracking ring did not change outcome of a tracking test in pitool/ calibrator. only plugging out eye tracking would turn off the leds.
Got a reply from support, they forwarded my ticket to 7invensun so we will see what happens next.
did the ring of tracking leds light up for you?if not we are probably in very similar boat.
Nope no lights

So how many have received the ET so far, and how many of those were able to get it to (1) work, and (2) function properly with dynamic foveated rendering ?
I have not, because I decided not to buy it. I really wanted it, but I was concerned that no one had been able to test it and post their impressions.
Now I am really glad I opted not to get one. Iāll use that $100 towards a new RTX 3080 instead.
Got mine, early batch 2 I think.
1 Mine works
2 Canāt test as I donāt have a RTX card
while the eyetracking is definitely a mess at the moment I donāt think the 100 is going to put much of a dent in the cost of 3080! 
Hereās some instructions

The code above matches the code I received.
After all, it was a fixed code, not a personal code or a disposable code. HAHA
My eye tracker is initially recognized as Droolon Pi 1.
So maybe I donāt need to go through this procedure.
What is the next step?
I just received my ET too. Okay, fine, here it is then.
So letās wait for more people having successfully made it work before I even bother to unpack it.
By the way - is there any information whether the ET is supposed to improve the distortion profile ? It would be very interesting to me because I suffer from some convergence issues, as I have mentioned in more detail in other posts.
whats the password for the actual rar
There is no information whatsoever. They just sent out the modules and released a new Pitool. For most it did not work at all and if you get it to work it leaves you puzzled with what to do with it or how to use it. There is no documentation, benchmarks, testing tool - or any sort of information about it. Itās Pimax communications at its best once again.
Theyāre the first company worldwide to bring eyetracking to the gaming consumer and yet again they completely blew it to make something out of it.
The unzip password?

Iām the biggest Pimax fanboy there is, but even Iām amazed by their incompetence sometimes.
what the hell is that?
Is it not possible to change the language of the installation to english.
I have no patience to solve problems with Pimax in the forum. I think I will switch to HP Reverb G2 now.
