Wondfo One Step Ovulation™
Easy to read and can definitely tell when ovulation has occurred!
My true positives on these were very obvious, with the test line being much darker than the control. But I had a couple "fake positives" where the test line and control line were definitely the same colour, but it wasn't my surge yet (tested the same urine with other brands to be sure). On an OPK I've always read that for it to be positive the test line has to be AS DARK or darker than the control, but with these I often got lines as dark as the control and I wasn't ovulating. A quick test on a cheapie dollar store test can confirm if you're truly ovulating or not though so it wasn't a massive issue. Otherwise for the price these are amazing.
I love the price and the effectiveness! Really helps you understand your cycle better and not have to guess as much about when ovulation occurs!
Easy to use and inexpensive! Great for those that are on fertility treatments!
These ovulation tests are easy to use, develop quickly, and easy to read. When bought in bulk sizing they're extremely affordable and with the larger inventory at home you never have to miss a surge because you're being stingy with your tests! There is no brand I would rather use.
Great price, great product! No need to use any other opks these work perfectly.
I find these easy to use and easy to read. I'm not sure why someone said it's hard to see. Mine are clear and easy to see the difference of when I am ovulating and when I am not.
I personally love these. So affordable, easy to order in bulk on Amazon, and after trying a few different brands of "cheapies" I noticed the dye on these were much better than the others. Very easy to read!
So impressed with this product! Does exactly what it's supposed to and the price is perfect!
I found that the lines on the strips weren't always easy to read because they were too faint. The dye is really bad.
It takes a little getting used to but is very clear when ovulation happens.
