Digital Basal Body Thermometer, 1/100th Degree High Precision, Quick 60-Sec Reading, Memory Recall, Accurate BBT Thermometer for Natural Ovulation Tracking by iProven

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.

Update 11/7/24: This company was super great to work with. They saw my complaints, and sent me an upgraded version of their thermometer to try. It works great! It lights up, the numbers are large, and the button is easy to press. And it's easy to look back later at the temperature that was taken to record later if I want to do it that way. The customer service was top notch, so I would order from them again now. Original review: I wouldn't order this again. I didn't realize that the temperature doesn't light up. So since I'm using it for taking BBT first thing in the morning before getting up, it's dark, and I can't see the temperature. So then I have to come back later to actually record the temperature. I don't like the way you have to hold the button down in order to get the prior reading instead of it just showing it like others usually do. Also, pushing the button is kind of difficult. I wish it was a bigger button. I also question the accuracy a bit since it measures way different than the other thermometer I had. I got it to have more precise measurement since my other one only measured to one decimal point, but this one will measure at least .5 degrees off from other other one.

The thermometer I received didn't work, and the included replacement battery didn't fix it. I reached out to the company's customer service directly via email, and they replaced it for me at no charge. I didn't even have to send the broken one back! The new one works perfectly, is easy to use and easy to read. Highly recommend this company!

It’s a great thermometer, just takes a while to get your temperature!

Great thermometer, quick results!!

Arrived quickly, as described, and works well. The display is plenty large enough to read, and lights up when you first turn it on, and again when it's finished the reading, but the nice part is it goes dark while in use so it's not shining in your face. It stores your last reading in memory and shows it when you first turn it on, in case you can't write it down right away. Easy to use, easy to clean, good design. The beep when it has a reading is not quiet, but much quieter than other models, and only one semi-long beep, not a persistent beeping. I wrap my hand around the bulbous end and it mutes it a little bit too. :)

Ssave yourself and buy ine with a large screen that lights up. BBT in the AM in dark or even slightly dark room is impossible to read the sccreen.

I was able to try both thermometers, so here's my feedback that will hopefully be useful for the next person. I originally ordered the thin thermometer but there was an issue so then I tried the one with the bigger screen. If I had to choose between the two, I would prefer the thin thermometer. The thin thermometer is your regular, basic bbt thermometer. To use, you turn it on, it beeps, then stick it under your tongue, all the way to the back (on either the right or left side), when you first wake up in the morning. It's best to have at least 4 hours of uninterrupted sleep for the best accuracy. Then it beeps twice, and then you can remove it from your mouth. You would then log your temp and the time on your bbt chart. If you wake up and it's still dark, you'll need to use a light source like the light from your phone screen to see the numbers. You can also just read your temp later on in the day when you're more awake because the thermometer remembers your last reading, but be sure to note the time that you took your temp. The bigger screen thermometer is more for someone who prefers to read bigger numbers with a backlight. You won't need a light source to see the numbers because it's already built in. The beeping sound is also louder. I wake up early when it's still dark so I did find the backlight blinding and the beep startling when I'm still groggy from waking up first thing in the morning. To resolve the light issue, I just flip the thermometer down. I haven't found a fix around the louder beep yet. Hope this helps!

Only a small little one, but I have to say it works well and it does the job so I can’t complain about it. I would highly recommend this if you’ve got little ones in the house. You don’t need extreme expensive ones for them to work.!

كيف اعرف درجة الحرارة بالفهرنهايت حتى البرنامج مو راضي يقبلها ولكن للاسف بحثت كثير في اني القى ميزان جيد لذا الموضوع ومالقيت

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.

Funktioniert wie ein normales Thermometer, zeigt aber 2 Nachkommastellen an. Wenn die Genauigkeit stimmt gibt es nichts negatives.

Parfait pour la sympto, dommage qu’il n’y ai pas de rétro éclairage mais j’ai pris l’habitude d’emporter mon thermomètre dans la salle de bain en quittant mon lit. Le bip est discret, ne dérange pas mon conjoint.
