And the light mechanism is so finicky, it doesn't work how it’s supposed to at all. At the time of purchasing this, this product was the only ovulation microscope available, and too bad because it’s very low quality. I will be looking for another one thats made better. ## Features - Accurate Ovulation Tracker: Clinically tested in the USA for 98.9% accuracy Ovulation Test Kit uses advanced saliva-based technology to precisely track your ovulation cycle, helping you plan your family with confidence.

And the light mechanism is so finicky, it doesn't work how it’s supposed to at all. At the time of purchasing this, this product was the only ovulation microscope available, and too bad because it’s very low quality. I will be looking for another one thats made better. ### ⭐⭐⭐ Works, but cheaply made *by A***N on April 15, 2025* It does what it’s supposed to do but it is extremely cheaply made with flimsy plastic and it is difficult to turn the light off. I do appreciate the extra batteries being included. The packaging had clearly been open, however, the item appeared unused so I did not return it. Shipping ended up being much later than it was promised to be delivered by. ## Frequently Bought Together - KNOWHEN® Saliva Ovulation Tests Kit – Non-Invasive Ovulation Predictor kit, Unlimited Tests for Fertility Tracking – No Waste, No Urine Mess – Hygienic Ovulation Days Tracker Kit for Family Planning - Pre-Seed Fertility Lubricant, For Use by Couples Trying to Conceive - Easy@Home 50 Ovulation Test Strips and 20 Pregnancy Test Strips Combo Kit, (50 LH + 20 HCG)-Package May Vary --- ## 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.pt/products/658536476-knowhen-saliva-ovulation-tests-kit-non-invasive-ovulation-predictor-kit](https://www.desertcart.pt/products/658536476-knowhen-saliva-ovulation-tests-kit-non-invasive-ovulation-predictor-kit) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-05-12*
