Wondfo - 50 Count Individually Ovulation Test Strips - Detecting LH Surge & Highly Sensitive at Home Test Kit (50 Count) - W2-S50

I've tried a few different brands of LH strips, and this one works best for me. I pair it with the Wondfo qualitative tests because I like to see positive/negative in addition to the numeric levels. I'm not sure that it's perfectly accurate, but it works very well for my purposes. Sometimes this will show 25 when the qualitative strips are still negative, and sometimes this shows much higher than 25 when qualitative strips don't show a strong positive, but maybe it's the qualitative strips that are less accurate. It's simple to use and the lines are pretty clean (not streaky). I would recommend going with your instincts when trying to match the color on the line up to the color on the card, because if you overthink it, a 5 can look like a 25 (but not like a 10). If qualitative strips work for you, I would recommend those instead of these just because they're simpler and less expensive. If you want the numeric levels, this is the best I've found.

These are so much more affordable than the pee-on-a-stick kind and they're the same thing (maybe a little less convenient). They're perfect for anyone who wants a little extra peace of mind whether it's watching that second line get darker or making sure there's only one line without breaking the bank. Used these for four pregnancies and they're correct each time-match what a pricier name brand read.
