Frer false positives or indent lines ??

[mzzducky]

So I haven't been back to dollar tree yet but was given a 2 pack of frer..
I'm in Canada if this makes a difference

Now when I take the test instantly a line shows up.. but here's the thing it looks like it has no color... by the time it hits about 8 min. That line Is barely even visible like a real squinter .

Does anyone else have these issues ??

This is the last test I took.. fmu..
