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.

Works Great!
Works great! I use this every morning and it is super simple to use, clean, and is pretty accurate from what I can tell.

Great Thermometer with minor design flaws
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!

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!

Didn’t work. Make sure to get a thermometer with a screen that lights up
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.

Long lasting
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? LolIt 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.

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.
