Thank you ### ⭐⭐⭐ Not very happy *by V***A on 29 January 2026* Very slow and doesn't always work ### ⭐⭐ If you like loud pointless beeping in the morning *by A***R on 25 April 2025* 10 loud beeps supposedly indicate that the temperature has been taken, but it’s completely inaccurate & extremely annoying first thing in the morning. Even the instructions say to wait 3 minutes, after which I’m still not convinced it’s entirely accurate, regardless, why not just set the beeps to go off after 3 minutes?! And maybe not 10 of them? Trying to conceive is hard enough thanks. --- ## 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.be/products/129442650-beurer-ot30-digital-basal-thermometer-with-bluetooth-data-transfer-pregnancy](https://www.desertcart.be/products/129442650-beurer-ot30-digital-basal-thermometer-with-bluetooth-data-transfer-pregnancy) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-28*
