Query: DO NOT BUY THIS PRODUCT!!

I wasted $15 and 2 months on this product!! I thought I was missing my ovulation days because my cycle has been somewhat irregular. Turns out the product does not work. I just tested with these strips and a First Response strip. According to this strip, I am not ovulating and the First Response strip indicates that I am. Do not waste your time and money on this!
