The price looked good, others seem to have good results, and not really sure what the difference is between brands we gave this product a try. My wife just followed the instructions and it's been working for her. It showed her peak ovulation this month was early this week. Feeling pretty good this might improve our chances of her getting pregnant soon and hopefully we don't need to do anything more involved. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Positive result shown in just 3 mins!!! *by E***T on Reviewed in the United States on July 20, 2017* I have been testing for a while and haven't got any positive results maybe bc i am still breastfeeding my 11months old 4 times a day. Tonight, I decided to test again, and finally the LH surge shown up. The positive result shown up very fast within 3 mins as you can see from the picture I took; the background still hasn't cleared up yet at 3 mins, but already shown very positive. I guess the recommendation of testing at noon dosen't work for me. ### ⭐⭐⭐ 3.0 out of 5 stars They didnt work for me but we are trying to figure it out *by M***N on Reviewed in the United States on June 24, 2017* Update: this company has excellent customer service. They are helping me to find out why mine didn't work. I've see the pictures of thier product testing. And they honestly look exactly like what i wanted. Im stumped. But they gave me a full refund unsolicited! So they really aim to please. I hope to update with a reason to what went wrong soon.I have tested many many opk brands. My favourite is not available now. But these looks like they were the same. They are not. And I almost missed my surge because of them. Not one test was positive.1st picture is all the preknow brand cycle days 13-172nd picture I took another test cycle day 17 eve because the 1st was so close. And dipped my favorite test (choicemmed brand top) (preKnow bottom) my favorite, tested and trusted brand is clearly positive! While this preKnow brand is negitive!Picture 3: cycle day 18 my trusted brand (top) is just under positive. Surge is over. And preKnow negitive.Conclusion you will miss your surge if you use these tests. They suck. Honestly I wouldn't use these tests if they were free. I am very sad my favorite got replaced. But my second choice is iproven. Read right @ 5 min they are very accurate and well made. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/43306081-preknow-50-ovulation-test-strips-and-20-pregnancy-test-strips](https://www.desertcart.id/products/43306081-preknow-50-ovulation-test-strips-and-20-pregnancy-test-strips) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-13*
