Not the product advertised in picture
I have the old clear blue fertility monitor and had been struggling to find the sticks compatible with that monitor. The advanced sticks don't seem to be compatible with the old monitor as they will register "high fertility" for about 14 days, but never "peak fertility". I bought these as the product pictured was the old type of stick, but I was sent the new kind of stick to be used with the advanced monitor. Disappointed, therefore, with this product.
