Is that line there in the case as well?
i don't believe that one person could have that many evaps so I think something is going on. I know you've been put off tesco blue dye tests but I only used them with my son who is now currently smearing toast all over his mouth and they were obviously genuine positives (also from 2015) so I'd say they were reliable
Wow don't know what to say! Those lines aren't in the right place. How bizzare !
It's thin but it's blue!!! Not sure it's an evap... can you try another frer ? U poor thing how frustrating!
