Product Reviews of 3M Digital Basal Thermometer

Product Review: My wife used this Digital Basal Thermometer, and ...
Summary: 5 Stars

My wife used this Digital Basal Thermometer, and she said it's a wonderful product. It's very fast (takes about one minute), and easy to read (digital display). Plus, it remembers the previous morning's temperature if you forgot to record it. The instructions are very clear and easy to follow. Overall, this is a great thermometer for women who want to achieve pregnancy (or avoid it).

Product Review: Not as precise as glass, plus loud beeping
Summary: 3 Stars

I bought this digital thermometer as well as a glass one. Used them both for a week to see if they gave me the same results. The digital one was really all over the place, indicating to me that it is not very precise. It may be "good enough" for the purposes, but I personally would rather use the more precise glass one. Also, since you need to take your temperature first thing after you wake up in the morning, the loud beeping from the digital thermometer can get really annoying.

Product Review: Not sure about accuracy
Summary: 3 Stars

My temperatures have been erratic all month and I can't tell if it's me or the thermometer. So I took my temperature three times this morning, one after the other, within a 3-minute window--I'd just woken up, and the only movements I made were to hit the button after each temp reading. The thermometer's reading changed each time, going up by .3 degrees overall. That may not seem significant for general use, but .3 degrees can make a big difference in accurate fertility charting.

So then I took my temperature three times within the span of about five minutes one evening and got readings of 98.6, 98.3, and 97.7, making for a .9 degree difference between the first and last temperature while sitting still. That seems incredibly unlikely. But how else can I test it?

So now I don't really trust the thermometer. I'm either going to change the battery in this one or buy a standard mercury thermometer for next cycle. I give it three stars because the delivery was prompt and it may be just me.

Product Review: PROBLEMS AND SOLUTIONS
Summary: 5 Stars

First of all, I really love this thermometer and all that it has to offer. The continuous beeps really do help to know that the thermometer is in the proper position. It normally takes me less than 30 seconds to get a reading and its great that it beeps when its done. The memory recall feature is definitely a plus, esp. when I'm still too drowsy to remember the temp, and the back light feature is equally great. I think this is one of the only thermometers with a backlight. I've been using it with success for the FAM for almost two years know. I would definitely recommend it to a friend.

I've been reading the complaints that people have and a lot of them aren't valid or easily solved. Here they are:

PROBLEM 1: This thermometer can't be used as a basal thermometer or to track fertility because it doesn't record to the 1/100th (like 97.39) of a degree.

Answer: FALSE!! Tony Weschler, states in her latest edition "Taking charge of your fertility", a groundbreaking book on the subject of the Fertility Awareness method (and in turn NFP)--just look at the reviews on it here on amazon, on page 76 "Also, it is imperative that it be accurate to within 1/10th degree F. (for example, 97.4), BUT DO NOT USE THOSE THAT MEASURE TO WITHIN 1/100TH of a degree (for example, 97.47) since the latter are unnecessary and confusing." (emphasis added)
-------
PROBLEM 2: The beeps are WAY too loud. They annoy me and wake up my spouse.

Answer: I personally don't find them to be too loud and neither does my husband, but if you do, on the back of the thermometer there is a small hole for the sound. When you're taking your temperature. Simply take your thumb and lay it straight down the back side of the thermometer while it is in your mouth, so that the hole is covered up. I found that this will SIGNIFICANTLY decrease the volume to a quiet, muffled, beep. You can even wrap your index finger around the top part of the thermometer (where it says BD) to give your your thumb some more resistance to press up against, muffling the sound some more.
-------
PROBLEM 3: The back light doesn't come on when it's done taking my temperature.

Answer: When it's done taking your temperature, press the button to turn off the thermometer. The back light will turn on again, revealing your temperature before it shuts off.
-------
PROBLEM 4: For the memory recall feature, the reading doesn't stay on long enough for me to be able to record the reading, and then it is erased.

Answer: When you turn the thermometer on, your last temperature will be displayed for about 4 seconds. If you turn the thermometer off again before it starts taking a new temperature (when it starts to flash), your temperature will actually still be stored on the recall feature. So when you turn it on again next time, it will still be there and continue to be there however many times you do this. Also if the 3 seconds you had before you pushed the off button weren't enough for you to see your temperature, you'll notice that you'll get an extra 5 sec's to read your temp when you press the off button before it finally shuts off.

I hope this helps!
