BeurerOT30 Digital Basal Thermometer with Bluetooth Data Transfer and Pregnancy Planning App, Displays Results in 3 Minutes, Suitable for Oral or Vaginal Use

Small, comfy to do vaginal BBT, beep just loud enough to hear. The battery was nearly flat when I received it, but I've been using it daily for a few months, and it's only gone down a bit, so not overly concerned.

Good quality thermometer by a trusted German brand.However what really annoyed me is that the packaging and pictures here on Amazon suggest that this product comes with premium access to the Ovy app, which it doesn't. The basic version of the app is free, however that version is completely useless if you want to use it for fertility tracking because in that mode you can only track your temperature, not other crucial factors like cervical mucus.It is really disappointing because it seems they were deliberately vague in their product description and references to the Ovy app to make people buy the product.I contacted their customer service about it and they were also not helpful at all, instead they replied with a condescending response suggesting it was my fault.This thermometer is no better in its use together with that app than any other cheap basal thermometer!

Product advertising and packaging is misleading. Thermometer does not sync with the app and data has to be entered manually. Also it is only the basic free app, I thought they were providing access to the full app. The reading time for the thermometer says it is 3 minutes, it is definitely a lot longer than that, well over 5 minutes for the first reading. It says it has automatic storage of the last measured value, which is completely inaccurate every time and displays the wrong previous temperature.Only just received but seems to be working fine so far. But false advertising.

Needed it for potential illness. Other thermometers are SO expensive...It takes a while occasionally, to get a reading though.

Only using to take temperatures whilst in Lockdown, but very easy to use and keep clean and sterile! Thank you

I purchased this item to take body temperature , a previous reply to a reviewSaid it could be used as such.Thks individual thermometer is not accurate by 4.00 Celsius ..I would not recommend this a a body temperature thermometer.

Bluetooth sometimes works, but 80% of the time I had to manually add temp into the app. Product arrived with 30% battery…! Had to buy more batteries online. Can’t get hold of the company to return this??Also from mum-to-mum, waiting 3mins to record your temp whilst you have babies and toddlers in the room (because you take your temp when you wake up in the morning) just isn’t convenient. I’ve now bought a cheap digital thermometer that takes my temp straight away and I record it straight onto my phone. Takes less than 30 seconds.Wish I could figure out how to return this Breuer :/

I should have paid more attention to the negative reviews.It doesn't work reliably at all - consecutive readings give completely different results. Going to return to amazon and pay more for a better one.
