First of all: The delivery was fast and without problems, shipping in a neutral and discreet envelope. The 12 thin packaging of test strips that makes sense. With enclosed is an instruction manual, but really the test is self-explanatory. Simple urine in a clean cup field, immerse the test strip for 5-10 seconds up to the mark and wait. A line does not get pregnant, two lines pregnant ... just as with other tests also. AAAAB ... and now the crux of why I forgive only 3 stars Unfortunately, these tests have a strong tendency to these so-called evaporation lines. That is, the marking of the test line (ie the line that indicates whether you're pregnant or not) always turns easily and is visible and that unfortunately not only similar after 10 minutes Often even within the first minutes and for that I am extremely angry. If woman has never heard or read, could here quickly arise false hopes to be pregnant, because often the pregnancy hormone is precisely in early pregnancy is still very low and fine delicate lines have emerged quickly. Unfortunately, the factory often confused with these evaporation lines if you are not familiar. And this phenomenon I had unfortunately almost always, not just in individual tests. Here's my tip: evaporation lines are generally thinner than the control line, grayish and clearly visible when you hold the test at certain angles, unfortunately kept light often also so.Gegen the (day), can be seen mostly nothing. Correct positive lines are pink, as wide as the Line of Control, to recognize in any angle and also against the light.
