Excelente
El termómetro es excelente y preciso. Muy fácil aprender a usarlo, la correa es ajustable y trae una extensión por si hace falta. La mejor manera de obtener la temperatura basal de forma precisa y sin preocupaciones. Super recomendado

Great, but have extra batteries handy
Really like the product, super accurate and so much easier than a thermometer in the morning. You might want to spend the money and get the newer version, the battery on mine died within a month. Luckily, I had other button batteries and it comes with a tool and instructions, super easy fix, but I wasn’t expecting to change the battery so quickly.

The only way to track your BBT without waking up at the same time every day as far as I know…
With a traditional BBT you have to wake up at the same time every day to get an accurate reading, not with the Tempdrop! This is the whole reason I bought it, and for that, it works great!It’s not uncomfortable, although did take a few nights to get used to. I had it over a year before I had to change the battery which was easy to do. I would prefer if it had a rechargeable battery that I could plug in to charge or even a small charging stand that could live on my bedside table with the Tempdrop.There’s only one button, so at first I was not sure if it was recording my temp or trying to Bluetooth sync but it’s easy now that I’ve got the hang of it. The bluetooth sync does take a minute or so, it feels like forever when I’m trying to get ready in the morning.I don’t use the Tempdrop app, I just copy the reading over to Kindara. I wish it would sync with Kindara automatically, I have years of data there and I’m just not switching charting apps to use the one that comes with a new device.It is slightly overpriced, I don’t think the technology (a thermometer and Bluetooth device) is that revolutionary that it should cost nearly $200 (at the time I bought it). I think the price is coming down but that’s probably the main thing stopping most people from trying this. A traditional BBT thermometer is a couple of dollars at the drugstore (free with some NFP classes). Even if they lowered the cost to $30-$60 I’d bet many many more people would try it because tracking BBT is truly a pain without it.Finally, the Tempdrop team seems reluctant to advertise that it can also be used to help avoid pregnancy (as well as achieve it). However, I think if they leaned into the TTA market it would be great for the company and consumers. I would love to see this company succeed because I love the product. I love tracking my cycle/charting, it helps me know my body and feel empowered and I would love to see more women get into it. Right now, the price of the Tempdrop is exclusive but it’s a great product and I think if they lowered the price and expanded the market it could be even better.

Broken and Useless
Updated Again to add: after inconsistent use for 3 years (only for a few months when I’m trying ti get pregnant) this tempdrop has been rendered completely useless. I have to open the tempdrop every time I try to use it because it won’t turn on due to the cheap chip they use no longer working when it touches the battery unless I bend the gold parts back to touch it. and then when I try to sync it, I have to do it again which destroys the sync data. Completely worthless and not worth 170 dollars. You can buy a basal thermometer for 35 dollars, and you should at this point because tempdrop now has a subscription service for their product that used to be free other than the sleep data. Really shady and shifty, and sad.Updated to add: I used to be able to see ovulation predictions without paying the premium subscription. I got pregnant and stopped using the tempdrop. Now that I’m not pregnant I am using it again and I’m sad to see you need the premium subscription for any prediction and use other than just logging the temp. I have another fertility tracker I’m interested in that I may replace this with. I had the premium subscription before just so I could use the sleep tracking aspect of the app but now that I need it for every aspect of what this product is supposed to be used for, it seems really cheap of the company to essentially sell a permanent subscription if you want any ease using their $170 product.I use this for tracking my fertility and now I pay for the subscription to track my sleep and I’m really finding a lot of value in that. I’ve used it for a little over a year and just bought the subscription recently and it is really incomplete without it, in my opinion. I find overall value is 4/5 due to high price paired with subscription.The biggest thing that helped me was buying one of those arm bands you put your phone in while you’re running and putting that on my leg at night and slipping the temp drop in there between the fabric and my skin. It has to be tight but not uncomfortable. I store the tempdrop in the pocket when not in use. Keeping the temp drop on my leg (always same leg, same spot) has made this possible for me. Otherwise it fell out every night and I’d lose it. It has been incredibly accurate and on the dot for predicting my cycle.I plan on using it to try to get pregnant soon as well.
