I Like It But....App Needs To Be Better
I purchased this to help find when I am ovulating easier, and make it a lot easier to take my morning temperature on the days I either forget or I move around to much before taking my temperature and then I do not get a true reading. So far it works very well; however, the temperature is always lower than my Smart Basal Thermometer. I am not sure if where it sits on your under arm will always be cooler than under your tongue or if there is something wrong; but it has always been lower than my Smart Basal Thermometer for the past two to three months now. The arm band is comfortable however you do have to get use to it at first. But ones you are use to it then it is comfortable. The syncing is easy and really it does not take that long to sync. The app is easy to use as well; however, I wish there were more things to keep track of in the app. Furthermore, I wish it also synced with Apple Health too, and the graphs it puts out, I wish they were a little better than they are now. But all-and-all; it is still pretty good and I would purchase it again if I did not have one.

Buy from original website and get the insurance!
I love(d) my tempdrop. I tried BBT with just a thermometer for about a month before giving up due to too many inconsistencies that were out of my control: poor sleep & a puppy with a small bladder. A fertility specialist recommended the Tempdrop to me as a way to get consistent results and for TWO months it worked great. Unfortunately previously said puppy likes to chew on hard plastic items. The arm band smells just like me and she pulled it off my nightstand. It was destroyed :( Silly, stupid, sweet puppy cost me $160 for a two month product. If you are having trouble with BBT due to crazy sleep patterns buy this product - through their website. There is a $45 insurance option the covers accidental damage for 1 year. Do it! Now I'm buying this thing all over again. Product is great! Just get the insurance if you have a creature that likes to chew on expensive things.

Malfunctions after changing battery. Big hassle
Tempdrop was very accurate for me. I Love it! I think it would be perfect if after changing the battery it wouldn’t malfunction. Tech support is a nightmare. I say that because after almost a year of no problems and knowing the exact correct positioning I needed to contact them. My Tempdrop worked for a couple of nights after changing the battery then it wouldn’t download my info. Tech support told me it was either not turned on or in wrong position. I triple checked. Even though I knew it wasn’t either of those. I made sure correct position and that it was turned on. They were no help at all. It’s really too bad because like I mentioned before, Tempdrop is extremely accurate. I will not buy another one because of the malfunctioning after battery change and tech support. Apparently from reviews I’m not the only one.

It was great till it wasn't
It was great at first. We got this to help improve my awareness of my cycle and tracking my period/ovulation. Then one day it just randomly stopped working and wouldn't turn on anymore. We did all the recommended steps to fix the issue and it still didn't work. I've only had it for like 6 months. Super disappointed especially given how expensive it was. I'd rate it no stars if I could at this point.

Works great, not super comfy
Life changing for fertility tracking! So much easier than taking temps every morning. I do wish it wasn’t drop shaped, since it kind of stabs into my arm at some angles when I’m wearing it. Took a few weeks to get used to, now I’m not as bothered by it. It’s kind of annoying that it doesn’t sync automatically. I don’t keep my phone in my bedroom, so I have to make sure to remember to sync it every day or two. Overall worth it!
