Sweat bands

FUELERDUDE

I am seriously considering purchasing one (or a few). When I run, I sweat tremendously and I am tired of having to wipe it off of my face or stinging my eyes. To get on with it, I have some concerns. Are they comfortable? How many should I purchase (I'm presuming they should be washed after each use)? How likely am I to break out in a rash or pimples due to wearing one (I don't want a band of 'em around my head.). Do they help?

Any advice/help/feedback is appreciated.
