I'm selling my five days old Valve Index with only one base station of the HTC type 1(old type, new device), without controllers.
But for jittering after flying condor for a while, it works quite fine at 80, 90 and 120 FPS. 144FPS only for a short while.
It's heavier, yet more confortable to wear than the HP reverb, larger FOV and better adjustments, like IPD up to 70mm, lens to eyes distance.
I still decided myself for the HP due to the better native resolution of 2160 per eye.
If anyone is interested, please send me a private message.
See you up high
