Thanks - there are a couple things in the poll that point to that conclusion - OR - the conclusion that API tests are no 'worse' than any others.I'm seeing 3 times as many people vote for Option E than Option C. That makes no sense, to say "I think the kit has false positives" while "I haven't found false positives."
What I make of it is there are people voting for Option E that haven't used the test kit themselves. In other words, "I think this test has far more false readings," because someone on the internet told me the API ammonia kit is junk.
