4 evaps??

Tara
So I've taken 4 test 2 blue dye tests from the same pack and then 2 pink dye Walmart cheapies. All of them have had the lightest lines after the time. I know they aren't the best tests but having for evaps is that normal.. I'm just getting a little freaked out. I've had some evaps on the Walmart cheapies before but not in a row 🤔
