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

Broken with no way of rectifying
I'm really disappointed in this product. Used a handful of times and it no longer works. Can't get hold of the company either to discuss the problem. Such a waste of money!

If you like loud pointless beeping in the morning
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.

No premium app access as suggested
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!

Good product. Batt nearly flat when new.
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.

Not as advertised
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.

Not good at body temperature
I purchased this item to take body temperature , a previous reply to a review Said 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.

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

Ich habe mir dieses Basalthermometer vor ein paar Tagen bestellt da ich mich mit NFP beschäftigen möchte. Ich habe gerade auf Grund des stolzen Preises und der sehr durchwachsenen Bewertungen wirklich mit mir gehadert ob ich es mir bestellen soll, habe mich dann aber doch dazu entschlossen. Als erstes sollte man sich tatsächlich die Bedienungsanleitung durchlesen, dann können einige angebliche Mängel wie dass die Batterie angeblich leer ist ausgeschlossen werden, denn da steht drin, dass "low" nicht auf leere Batterie sondern auf zu niedrige Temperatur bzw. vor der Messung auf Betriebsbereitschaft schließen lässt und auch so einiges mehr was für die Messung wichtig ist, auf die man sich ja dann irgendwann verlassen will. Bisher sind die Messergebnisse bei mir absolut plausibel sodass ich keinen Anlass sehe von Falschmessungen auszugehen. Kleines Contra: Der Piepton ist wirklich extrem leise. Klar, soll es den Partner nicht wecken aber wenn es so leise ist dass man es selbst kaum hört ist das doch ein bisschen nervig. Das kann man jedoch gut umgehen, da das blaue Licht umso heller leuchtet und man daher weiß: wenn das Licht ausgeht ist die Messung vorbei. Und wenn man es doch mal verpasst macht man es einfach wieder an und der letzte Wert wird als erstes auf dem Display angezeigt. Die Bluetoothfunktion und auch die Speicherfunktion habe ich bisher nicht gebraucht, mir ging es nur darum ein funktionierendes, zuverlässiges Thermometer zu haben und das hat funktioniert.
