Product description
Does this basal thermometer have bluetooth?
No, this BBT doesn’t have bluetooth. You can manually enter your temp in your favorite app, or track it on the free chart.
Why does it take 60-70 seconds to take a measurement?
This ovulation thermometer measures your real body temperature. This takes a bit longer, but the results are more accurate.
Is the BBT accurate enough to determine my ovulation?
Yes. The BBT thermometer is developed to track your basal body temperature. Only a BBT thermometer is. It’s far more accurate and measures two decimals. This allows you to determine the increase in your temperature needed to detect your ovulation.
What is the best time to use the BBT thermometer?
It is best to measure your temperature with the BBT thermometer around the same time every day. The most accurate will come from measuring before getting out of bed, right after waking up. Your body temperature will be at its lowest during this time.

Works great and if not warranty/service is great
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.

Seems good
I have been fairly satisfied. It has been 5 months of using it almost daily and I have not had to use the 2nd battery they included yet. It is not readable in the dark, though.

Works well. Easy to use/clean. Nice display.
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. 🙂

I like it
Updated review: customer service for this product is top notch. They really wanted me to be satisfied with a thermometer and solved my issue. The second thermometer listed does have a light (with the larger screen). I got it 4 stars because of two reasons: the light stays on only briefly so you have to look kinda quickly, and this could be user error but there have been a few times (with each thermometer) that I thought it was ready my temperature but after over a minute I take it out and it’s just off.All in all, it’s precise to 2 digits and works for what I need!Oh, one more thing, the beep has woken my husband, so it’s not super quiet. Not a problem though since he’s usually awake before me anyways.And I like the case it comes in!Original review: I mean…I works…but heads up – there is no LED light. I know it’s supposed to be able to recall your last recording later but honestly it prefer one that has a light for easy reading without turning the room light on

Updated Review – Great Customer Service!
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.

Easy to use, great customer service
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!

Short Battery Life
Thermometer does as it should, reads temperature. I gave 3 stars because the battery died after 2 months of use. They do give a back up battery, which I was surprised to see, but now I know why. You can get the batteries cheap enough, you’ll just have to be replacing them frequently if your using this thermometer everyday for tracking bbt.

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.
