MABIS Digital Basal Body Thermometer for Ovulation Tracking, Fertility, Period Tracking and Natural Family Planning with Beeper and Memory, Oral Use Only

For the price, you can't beat this thermometer. I like that it reads to the hundredth of a degree. To ensure an accurate reading, keep it in your mouth for another minute after the beeps are done - and yes, the number CAN continue to rise after the beeps; it just can't decrease. I take my temperature in the middle of the night and either use my phone flashlight to read the number or wait til morning to record it (it retains only the most recent value). My one qualm is the battery cap pops off easily, but it's not bothersome enough to knock off a star. FYI, it will read temps over 100, but the hundreds digit won't display. So, it works just dandy as a regular thermometer, too, and will even do a special beep if the temp is over 100. FYI 2, "Lo" does not mean low battery...it means the temperature is lower than the thermometer "expects" and is waiting for you to put it in your mouth.For what it's worth, my SymptoPro course improved this device, and according to my instructor, my charting seems to be accurate. I would recommend this to anyone who's tracking cycle temperatures...no unnecessary bells and whistles, just does what it says on the tin.

Bought this thermometer after it was the most recommended in several groups. I had 2 main criterion when purchasing a BBT- 1) It has to have a memory recall - I usually take my temp around 6 in the morning and go back to sleep till 7. I wake up with my alarm, shove the BBT into my mouth, wait for it to beep, shut it off and go back to sleep. I manage to do all of this with my eyes closed. So, having a thermometer that records the last temp is super important. This BBT does exactly that(See below for how to see last temp)2) It should be fairly quiet- This thermometer beeps fairly quietly. Once when you turn it on and 4 short beeps when it’s done taking the peak temp. I usually turn it off as soon as one of four start beeping and go back to sleep. All of this takes less than 2 mins.This BBT is slender in frame and you can easily hold it in your mouth when sleeping. Overall, you’re getting a good quality, accurate, medical grade thermometer at a great price and I wouldn’t think twice about purchasing. Highly recommend.How to see last temp: When the thermometer is off, press and hold the power button. The last temp will be shown on the display for as long as you’re holding the power button. As soon as you let go, the bbt will go back to the self calibrated temp allowing you to take your new temp. Hope this helps.

I purchased this thermometer last week and have been very pleased with it. I use it to take my basal temperature each morning.Pros:- quick start up and temperature reading- beeps when it's done reading temperature- automatically turns off when not in use- one button operation (I consider this a pro because I take my temperature before it's light and before I'm fully awake, so streamlined operation is key)Cons:- the unit does have memory, but it's a bit misleading. You can't 'access' it (one button operation, remember). Instead, when you turn the unit on, it flashes the last temperature reading, then calibrates to 97.70, then flashes "Lo" to signal it's ready to read. The problem is that it flashes through pretty quickly. The only way to see it again is to (without taking a temperature) turn the unit off/on again.- not back lit. I don't consider this a huge problem since I just wait to read the temperature until daylight.*****UPDATE 8/21/2015So I've had this thermometer for about three months now and I'm having to purchase another one. My darling cat likes to push it off my nightstand and she's done it one too many times I think. When I picked it up off the floor this morning, it didn't display correctly. Some of the bars in the digits were missing so that I couldn't tell if my temp was 98.23 or 99.23 or something else. Anyway, the thermometer is priced well enough that I don't mind purchasing another one. This time, I'll keep it inside a drawer away from my mischievous cat's paws.For the record, I do not fault the thermometer for this as my cat really does like to push it off. She's pushed it off my nightstand at least twice a week (onto hardwood floors no less) since I first got it. I'm still very pleased with the product, just advice other cat owners to keep it somewhere safe.

I am using this to track my bbt. It seems to be consistent and works great. It stores two numbers until you take a temperature again. The first is the last temperature recorded which is a nice feature to so you can go back and record the temperature once you are actually awake on weekends. I have yet to figure out what the second number is though (this number has not changed for me and is always shows as 97.7) It makes a quiet noise so it doesn't wake your spouse but its loud enough that if you dose off while temping, it will wake you up to remove it. I see no reason to spend any more money on a fancier thermometer for bbt when this one works fine!
