iProven Basal Body Thermometer with Backlight & Big Digits, 1/100 Degree High Precision, BBT for Ovulation Tracking, 30 Memory Recall, Accurate Fertility Temperature Tracker

I feel the need to set the record straight.I just got my thermometer and can’t testify as to how well it works (I’ll update that later) but I can clarify a few things I noticed in reviews. Multiple people commented on getting a used thermometer with a temp in the memory of 105. My thermometer also said this with five temps in the memory going between two temperatures. I am 99% sure that it is factory testing. No reputable company sells a product like this without testing for accuracy and no one has a temperature over 105 without going to the hospital (first and last temps where 105 with middle temps being 98). Factories have controlled machines that test products before they are packaged (and packaging had no signs of being tampered with). That being said, you should always clean something before you put it in your mouth for the first time. It was made in a factory in China, who knows who touched it and if they had clean hands (anyone who works in a factory would tell you WASH IT before using).

Used it for 11 months and it worked great until it started failing. I couldn’t see the full screen anymore. I replaced the battery with the provided extra battery but it didn’t fix the issue. I contacted the company and their customer service was great! They sent me a replacement thermometer right away. It arrived quickly. Happy with this purchase and would purchase again if needed. Recommend.

I used this basal body temperature thermometer while trying to conceive, and it made such a difference. It was super easy to use first thing in the morning, and I loved how accurate and consistent it was. Tracking my temps helped me really understand my cycle, pinpoint ovulation, and feel more in control of the whole process. After a few months of tracking, I got my positive test! I’m so grateful for this little device—it felt like such a gentle and natural way to support our journey to baby. Highly recommend to anyone TTC!

Why did you pick this product vs others?:I chose this because of the 2 decimals. I am using it to track my menstrual cycle. It seems very accurate but the probe does take awhile to result

Works well and comes with an extra battery and a plastic container to store it in. Good quality for the price.

It is a simple design. Works easily

Because you have to take your temperature when you first wake up, having the reading be backlit would have been nice, I have to grab my phone, turn the flashlight on so I can light up the thermometer so I can read it to log the temp. Also, when I first wake up, I usually need to go to the RR, and having to wait over a minute for this to give me a reading then fumbling with my flashlight to get the reading is a bit annoying, my bladder gets grumpy.Otherwise, it's so inexpensive, and I think it's accurate but I have nothing else to compare it to, that it'll do. I wouldn't use this long term, just using this short term.

This basal body thermometer definitely does the job and is way more accurate than others I’ve tried. I also appreciated that it came with a spare battery—nice bonus!One thing that would make it even better is a backlight. It’s great that it shows the last recorded temperature when you turn it on, but reading the display while half-asleep in the dark was a bit tricky. Still, overall a solid thermometer for tracking BBT.
