Haven't really put too much thought into this, but the Walker tape does seem to give me a little itch after a couple of days. I have similar issues with some of the other tapes. It seems like some of them don't "breathe" as well as others. Really, only good ole' blue liner is about the only one that doesn't bother me at all.

Overall glues seem to work a lot better as far as this goes.

Another suggestion- use a liquid bandage in areas where you get irritation. I have had scalp irritation and had to re-attach immediately (and thus had no time to let my scalp rest) and used liquid bandage before I re-applied the unit with excellent results.
