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!

First one I received was defective seller replaced property at no charge new on works fine. I like the button placement on this one but it is a bit to large/heavy the black light is blue a very bright not awesome for 1st thing in the morning. I just dint look at it. When you check the recall for the last reading it doesn't stay up long enough that is a bit annoying. In the past my iproven thermometers came with extra battery this one did not just a case and instruction my last one was ruined replacing the battery for the 3rd time hopefully this one will fair better it takes a CR1632 *Orginal review *I've been using natural cycles app for almost 7 years so I've had several of these thermometers. This one is nice no loud beeb, back lite, easy button but does not read constantly or accurately enough to use with the app. It won't even calibrate 1st read was 97.68 next was 98.52 3rd was 99.14. The old stlye iproven thermometer this one was supposed to replace read 97.65 97.78 and 97.89 2 minutes later. So I'm not sure what the issue is with it but not accurately reading for me.

Great thermometer, quick results!!

Worked great for two months. Til I dropped it once maybe 2 week from a nightstand and it wouldn’t make sound and the temperature went completely out of wack

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. :)

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

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.
