product received very quickly. Very affordable rate. Easy to use. There is no need to be very pro to do, just follow the instructions: do not take the test on morning urine, dip the strip 10sec without exceeding the max line. Wait 10 minutes and hop ... easy reading. Remains to be seen if there will fertilization ... because even if the test is ovu + This does not mean that we will necessarily get pregnant as believed bcp. I am happy with the product and the réutiliserais the next round if I'm not pregnant.
