Basal Body Thermometer- BBT-113Ai-WG by iProvèn - Accurate 1/100th Degree, Highly Sensitive, Perfect Companion for Ovulation Calculator (Gray)

So, you've probably guessed I didn't much like this product! Lol.My beef with this BBT thermometer is that it's listing here makes it look like the perfect aid to women trying to track or predict their fertility and conceive through monitoring and tracking their core body temperature; you're getting all those functions in the unit (soft bleep - oh wow!), testimonials on slides saying how easy it is to use (it's a digital thermometer - turn on, open mouth, wait for the beep, done), and paragraphs extolling the simplicity and ease of this product. Thing is, when it turns up the box is the same size as a Vimto drinks carton but only half the depth. The guidance leaflet inside tells you all about the thermometers calibration, accuracy, how to use it, clean it, change it's battery..... But nothing about what your BBT is or how it works to affect, or reflect, your fertility cycle.No, for THAT information you have to go online to their website, slog through tons of other information and adverts before you get to the information you needed first off to see whether this would actually help for you.So I know theres an arguement for minimising packaging, etc, which I understand and accept. BUT, you've just paid £10 for this thing that does nothing more or less than other far cheaper products on here that comes with no additional information about how monitoring BBT helps with fertility or what you're looking for.And incase you were thinking "well, this thermometer will be more accurate than a cheaper one", reading the small print with this thing states: 'Measurement accuracy: +/-0.10C within 35.50~42.00C'. So, in the normal body temperature range, this thing can be out by 0.1 of a degree C when the whole point of monitoring BBT is to spot 0.1-0.2 degree spikes.Sorry, just not worth the money to my mind

Very easy to use - the leaflet that comes with it gives full instructions. Unfortunately there's no temperature chart included, but you can download it from their website. This is actually a good all-round clinical thermometer, suitable for monitoring fevers up to 42C, as well as what it's sold for. I'd have given it 5 stars if it was genuinely accurate to 0.01C, but according to the leaflet the accuracy is within 0.1C.

I’m really happy with this product. I’ve used it every morning for four days so far. I just put it in my mouth (touching the underside of my tongue) as soon as my alarm goes off to wake up. It works really quickly- usually about five seconds for me- and then gives off a gentle beep to let me know it’s reached my temperature. It’s very discreet and comes with its own little case so it stays hygienic between use. It does the job I need it to do perfectly, giving me my BBT to two decimal places. Very happy. Would recommend.

This thermometer is lovely and small and comes with a plastic casing. It works quickly, is easy to use and seems highly accurate. There is a chart to download to record your BBT which is a nice touch, though I think you'd need to print it (I use a separate app). Only thing missing from this model is a backlight - be aware, as I'm not sure that was clear on advert. Apart from that, super product for the price and nice quick delivery.

Super fast delivery as always - Brilliant thermometer - so easy to use and Simple well written instructions explaining how to use it. I was expecting a fairly simple thermometer for the price however it was MUCH nicer than expected ! You can tell it’s ‘quality’ and not a cheap gadget. This gave me faith in the product right away, very easy to take the readings each day and then simple to chart. The thermometer itself is nice quality, not lightweight, the digital screen is easy to read. It has lots of functions which was simple to operate such as mentors/ you can change the degrees from Celsius to Fahrenheit plus lots more. Def worth buying as superb value for money.

Good product, even better price and it does as it says in the info. Also comes in a nice little protective case. Very accurate reading, that’s why it takes a bit longer. To get the best reading, I put it under my tounge and close my mouth then press the button to turn it on as I wake up first thing as I’m using it alongside a fertility tracking app. Only thing I would suggest to improve this product is if it saved the last reading as you turned it back on because a few times I’ve forgotten to enter the temp in my app and it wouldn’t give an accurate reading if I did it while awake and moving around.

I love thos product so easy to use clear instraction very well presented quiet and i just love it xx

Thermometer never displayed a backlight so very difficult to read at 6am in the morning.But main problem - after 2 mths of tracking and only very erratic temperature patterns showing - I have questioned the accuracy of the device - now testing 2/3 times each morning to check accuracy and I get 3 completely different readings!No way of filing for a replacement in case this one is just faulty - so guess I will have to search for an alternative. Accurate readings are essential for us at this time. Very disappointing!
