I do not know if you can trust your computer

I have been around for a few years and 3 years ago had the device once in use and then taken the pill again for 2 years. While the device lying around unused it started from turn alone and to give modem noises. Only sporadically, at some point several times in succession and one day it just squeaked, so I had to take out the battery. Since the date of purchase had already exceeded 2 years, I sent the unit to change the battery, hoping the problem will resolve itself with battery replacement and maintenance. Of course, I described the error, if it has a different cause.

Exactly one day (!) Later, after I had sent the unit, I received a package with a new (I suppose used, generalüberholtem) device. They had found an electronic damage and changed the device even after the warranty at no cost. Here Thumbs up for customer service.

Now I could take the unit time with stopping the pill, before 4 cycles used. In the first month it was more than 20 days fertile. I wrote to the customer and this analyzed my values ​​within a few hours. It turned out that my curve was too erratic to encircle the infertile days accurately. Again, thumbs up for customer service.

Meanwhile, the device has detected my cycle better and showing more infertile days. But what surprises me is that no measurement is carried out immediately, brings the same result. Also, no comparison measurement with another device. The differences range from 0.15 to 0.2 degrees. Once I had a 0.2 degrees lower than my basal body temperature after waking up and Auftstehen. I'm really confused. I have also written to the customer and because they thought that the unit meets all the latest standards and the man is not calibrated. It could therefore lead to different measurement results, even if they were carried out immediately.

Now I bought a comparison nor the Domotherm the same company and both these devices show very different values, even if they are carried out at exactly the same time on.

I also have on my smartphone even an app that evaluates the temperature curves. These two devices show me to different results. Once I got in my app rather infertile days and last cycle showed me the app forever long fruitful to where me of Cyclotest long been barren indicated.

I really do not know if I can give the unit trust. I will continue to use the computer. Should he rausstellen be reliable, I'll update the review accordingly (of course the other way around). Luckily it was with me no "problem" to get pregnant ... it would be fine. Therefore, I take the risk.

Otherwise, there are at hand do not have much to say. It's just super convenient that only one must be measured and the device does the rest. No evaluation of the curves, no notes. Women do not even have eyes to make because of the large measuring button allows to feel with your eyes. As for general use, I give some previous speakers. Intiutiv you can not really use the device. One must study the arg operating instructions on Appendix already to know which button for what. Here is an inscription of the buttons would be really helpful. On entering fertility signs I have today also dispensed with since my already in the description is frankly too cumbersome.

Also, I find it somewhat unfortunate that you have to send the device to change the battery for 20 Euro. If then but the software and technical features are identical with tested, which is on the other side not bad either. And when the devices are always sent as a flash back, you can not complain about the response time also.

The processing of the device is aktzeptabel. And a beauty contest, it does not win.

I can currently say not absolute buy recommendation. With whom pregnancy would be no problem, it is how I try.
