Exceptional quality product. The ovulation test detects perfectly the period of ovulation and pregnancy test also are very reliable. I used the ovulation test that correctly detected my most fertile time. 17 days later, I make a positive pregnancy test the day after such +++ pregnancy test. A blood sample to the lab confirmed my pregnancy. These products are very interesting and super reliable. Feel free to those who want a quality product at low prices. The only problem is the thin strip. You can not urinate directly. So he first made urinate without a cup and then take the test a few seconds in the urine.
