I've bought these tests because they were very cheap. But I must say that the quality leaves much to be ... but you definitely more fun when you opt for a more expensive test ... it saves at least an unnecessary disappointment. I have the test at NMT + 1 negative getest, only to NMT + 3 was a very slight second line to see, while another early test (Pregnafix) already had a very thick Zwieten line. If I had to take the One Step Pregnafix already at NMT + 1 used, then I would have known earlier that it worked.
Each woman produces different rates HCG, thus it is also to explain that the test earlier strikes in some and in some later. Nevertheless, I would expect pregnancy symptoms a second line at NMT + 1 and already several days.
The product is a disappointment and I definitely would not buy it again.
