Hello, i was reading a post*1 where someone had the same issue with the TP sensors and got a replacement unit and that solved it and mentioned oxidation.
i was wondering if this is normal:
notice there's some discoloration on all the sensors, and is not consistent, it looks as it fades. in the image it seems like a shadow but it should look flat i checked there was no shadow.
it looks as if it's either dirty or transparent. all the sensors have a bit of that. but the sides ones are clearly noticeable on the outside vs the inside.

unfortunately i don't live close to the us or uk. and i've already marked the unit with a marker :/ and i don't think ill buy another headband, specially if the new one came used/damaged.
