o.k. i had 2 one of which if plugged in the firing button light just blinks does not seem to take a charge my other i have no problems with they are not 3.0's the originals i really like them for size and ease of use so i'm assuming that the blinking is basically saying excuse the language but is it telling hey i'm f'd or is it something else??? if anyone has had this or knows if it is just dead and gone or otherwise please advise
