Simple and effective! Baby 2 designed with these tests. Reliable ovulation date indicated, I had read that this also could detect early pregnancy and indeed, a week before the positive pregnancy test! If some do not have the two visible bands is that it is poorly made, is that there is an ovulation concern ... I was skeptical, especially given the price difference with other well-known brands, I am very satisfied and I plan to recommend for the tests of the last baby!
