Fertility Basal Thermometer for Ovulation - iProven BBT-271B - 1/100th Accuracy - Trying to Conceive The Natural Way - Monitor Your Waking Temperature - Ovulation Tracking and Prediction

This is a great product! It is very quiet when I use it. I don’t wake my husband up when it beeps. It is very accurate and it has nice colors. I highly recommend this to women who are TtC or trying to prevent pregnancy. This is a great product!

My old thermometer didn't register temperature for some reason. I checked it when the COVID19 situation started. I tried to find one like everyone else and had no luck. Then I remembered another way to go-the basal thermometer. It should be very precise. I fortunately have not had to use it yet, but considering that I have nothing else, the fact that it turned on is a plus!

This thermometer is accurate but difficult to use. It is very inexpensive and I found mostly good reviews about it, however the quality matches its price. I have to press the button really hard to turn it on and off and to get the last temperature reading I have to hold the button down for 3 seconds. However this is impossible most of the time since the button is so difficult, it just turns on or off a bunch of times. Only if I'm lucky it will actually work. Maybe I just got a messed up one and the others are better. I will be returning it though and I don't reccomend buying this thermometer.

Thermometer works as intended, my main complaint is there is not light to the display and the “case” is a poor afterthought. The display - The temp must be taken in the morning prior to getting out of bed, without a backlight in the device, you have no way of seeing the reading without disturbing the other person sleeping by turning on a light. The case - the device rattles around inside the case, causing further disturbance. After using the device, placing it back in the case is unsanitary and quite loud. The case can be discarded, as far as I’m concerned. I would rather have a case that fits the device snuggly and doesn’t make screeching plastic noise.

Great thermometer for checking your temperature during ovulation. Cute colors add a little boost of happiness in the mornings and make it easy to grab from my nightstand! Of course, it can also be used for checking your temperature when you or family members are sick so that's great as well!

I’ve been using this thermometer for a bit over three months, and up until now I’ve been happy with it. It’s easy to use and store, and the beeps are quiet enough not to wake my husband up. Over the past week or so, however, my temperatures have been lower than usual, and there wasn’t a clear temperature shift the day after ovulation. I tried leaving the thermometer in for longer, and it turns out it is beeping before reaching peak temperature. I can still use it by leaving it in a minute longer, but I have less faith in the readings now (not to mention this month’s chart is no longer accurate), so I will be getting a different thermometer.

I can’t speak 100% for the accuracy because I plan to use bbt to avoid pregnancy but I cannot rely on it quite yet because my 3 month old still regularly wakes in the night and thus I am not getting enough sleep to temp regularly. I wish I could get a faster reading but I guess it’s about right for a bbt thermometer...accuracy requires patience!

I unfortunately got a refund I did not ask for and have no clue how to get amazon to give the money back to proven but the packaging and everything is so nice and it comes in such a pretty box! The thermometer is so pretty!
