Good product so far
Doing it's job so far. No complaints. Can't advise on accuracy as I have nothing to compare it to. Only used it 4 or 5 times so can't comment on battery life etc right now. Have purchased it as another way of tracking fertility as advised on a fertility app.

Laborious C/F conversions required
It started on but soon after that I had to keep pressing C/F as it wouldn’t remember the Centigrade preference . Then it wouldn’t allow me to set Centigrade at all … meaning I have to do conversions after each reading . Laborious !

Ich bin absolut begeistert von diesem Ovulationsthermometer. Es ist super einfach zu bedienen, liefert sehr schnelle Messergebnisse und vor allem: extrem genau. Die Temperaturwerte stimmen zuverlässig, sodass ich meinen Zyklus und meine fruchtbaren Tage sehr genau verfolgen kann. Besonders praktisch ist das klare Display und die unkomplizierte Handhabung – morgens kurz messen, ablesen und fertig. Für alle, die ihren Zyklus genau im Blick haben möchten, ist dieses Thermometer wirklich eine tolle Investition. Präzise, zuverlässig und einfach in der Anwendung – ich kann es nur empfehlen!

I have bought this 2 times. The first one lasted 3 years, and maybe it would have gone longer if I hadn't lost the replacement battery - but alas I bought a new one instead. The new one worked almost identically for just over 3 months, and then started acting up. Obviously amazon return was out, and the manufacturer says 100 days full refund, but I was about a week over that when it quit. Given it also has a 2 yr warranty and I had used the other one for 3 yrs, I emailed the manufacturer and they quickly got back to me. They suggested a trouble shoot and offered id it didnt work they'd mail me a new one. The troubleshoot didn't work. After letting them know they immediately sent me a replacement without any struggle. I am impressed. So while my 2nd one did have issues, I give this 5 stars for history and a company standing by their warranty. The thermometer measures fast and accurately. The Last feature is nice.

Using for Basel temperature. It does take up to 60 seconds to get a reading as it’s more precise, so bear with it. It was set to F first then was able to change to °C. Saw good and bad reviews and the overall great rating so gave it a try and happy with it.
