Ok, another question for all of you
extender users. How many of you experience some "discoloration" of lower portion of the head (front of the fireman's helmet)? By discoloration I mean that it looks whiter than the rest of the head. I noticed this yesterday and I have decided to take a little bit of a break from using the device, unless this is normal. I still have feeling in the questionable area, so I am not extremely concerned, however I am concerned enough to ask.
I typically wear the device for an hour max before I take it off for a little bit, a lot of times I wear it for 30 to 40 minutes and I almost always use little pressure (3 visible "bars").
