has anyone ever used these from Dollar general? how accurate are they? had anyone had a false positive with them? not that mine are positive, but is it a well known thing with these tests?

update #2

so I updated in the comments from this morning but I'm a poas-aholic so I took another one around 830. there's definitely a pink line. my only worry is the dye was running till around the 5 minute mark on the last 3 tests I've taken. the run goes away and at 5 minutes there's only 2 lines. and the test line is faint, but pink. do you think the dye run from the test could affect the outcome of the test being positive? I post some more pictures.
