I have only noticed the blue band once or twice for about a 1/2 second then totallf forgot about it....
It's not why I'm here so I never pay it any attention....
I looked at the double your mileage post but had NO FRIGGIN clue what the guy was talking about... I never seen the add only noticed the refertence to it
I got me a jerk-off flash light

$15.00 came with a baby one too. It works great, if you have 2 minutes to shake it BEFORE you need the light...
