printed a mod to increase the fov of the quest pro by moving the back pad down, i've never used the eye-tracking so i don't know if it interferes however my fov is taken up almost fully by the lenses. when i look down i can only see a little bit out from the corners. i thought i was done with my modding but i just found and ordered some replacement chink pads that are silicone so we'll see if those are worth it
