Just received these (12 packs 62%) and thought the blue dot means everything is ok. Came with no instructions but not difficult to figure out how to use. Well, upon reading the written indicator replacement instructions printed on the indicator, it turns out that blue is not the color I want to see in a new pack of 12 of these boosters. Ironically, they appear to be unboxed, meaning someone simply ripped them out of a large packet or box, manually counted them out for 12, and placed them in an envelope. All 12 appear to have the outer clear plastic protective film intact, but they are now all unusable. Sure it's only $9 plus change, but $9 is down the drain. It would take me 60 miles round trip to return them to the UPS store so it's a total waste.
