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.

Ive used this for BBT tracking for almost a year now. This thermometer is perfect. It has never run out of battery, it is very precise and it proven to be worth the money. The light feature is quite bright but thats a good thing. Easy to use.

This digital basal thermometer works excellently —it's accurate, reliable, and easy to use. However, there are two small drawbacks. First, the lack of a backlight makes it a bit tricky to read in the dark, especially first thing in the morning. I’d recommend the backlight version for easier use. Second, the power button is a bit hard to press, which can be inconvenient. Aside from these minor issues, it's a great thermometer!

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.

I bought this like 6 years ago and the screen finally gave out on me. It's worked amazing, and lasted WAY longer than my other ones (they lasted not even a year - but that was technically my fault cause they were the kind you have to shake back down afterwards, and I would accidentally hit them on something while trying to shake it down & I have a big mess to clean up. Lol) It doesn't have a backlight, but it saves the temp, so if you fall asleep you can see what it was when you get up, so I always did that. Who wants to try to record their temp when they're super sleepy anyways? Lol It seemed very accurate and I liked it so much I bought one for my sis-in-law. I will be buying another one soon to replace the one that the screen messed up on.

Maybe I have a faulty thermometer but it gives me a different reading each time, even when I do it back to back. Mine doesn't beep so I don't know when it's done (it says it is supposed to). It's important to know that this does not have a light on the screen so if you take your temperature each morning in bed before there is enough daylight in your room, you are going to have to fumble around to turn a light on or get the flashlight from your phone on to be able to read the screen. Any basal thermometer should have a built in light in the screen so you can read it in the dark because we are all obviously taking our temperatures in bed, in the early morning. And you're not supposed to move around a lot before taking your temperature. I'm super sad that I wasn't able to track this cycle because this thermometer let me down.

Works exactly as described, took a few days to get the hang of it but it’s great. The screen is large and lights up so I can use it in the dark easily and I appreciate that it saves temperature logs so I can go back and look later on. Great for trying to get pregnant, avoid it, or even just to understand your cycle better. I also use it when I’m sick and it works just fine for that too.

Security seal was cut and a new sticker applied. I thought I was buying this item new but it’s not. Just be aware when buying this product. The display is easy to read and thankfully it was easy to clean (just be sure to clean before use in case it’s a returned product like mine). It has one button and is easy to use but takes awhile to get a reading.

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

Parfait pour prendre sa température tous les matins. Rapide. Précis. Je suis contente de mon achat.

Great product. Fast delivery. Packaged well. Spare battery. Ability to save and read measurement later. F and C temp readings. .2 decimal places too.

Doing it's job so far. No complaints. Can't advise on accuracy as I have nothing to compare it to. Only used it 4 or 5 times so can't comment on battery life etc right now. Have purchased it as another way of tracking fertility as advised on a fertility app.

Really good product. Very accurate I recommend.
