The sensor is located on a long cable, which is wound on the back of the device in a heavy wind-up / closable cable drum. Since no automatic feeder is present, the cable must always consuming discounts and be rolled back. When closing the cable drum, the cable in a 5 mm wide recess must be threaded, as it will otherwise squeezed out of the cable drum. And by 5 clock in the morning (in the dark) when you want to measure. Very funny.
The keys are all unmarked and also have additional functions. If you press the button to measure too long, a new cycle is started, and thus delete all measured values of the past month. How does the device then you realize the last cycles indicate yes needed to ovulation in the device, the manufacturer can open the manual.
The device must be used for several months, before a (supposedly) present reliable indicator. Small measurement errors and operating problems preclude proper use of it maintains a solangen period -> Function = 0
The drivers are 3 years old, the latest is for Windows XP, but runs even on this. On Windows 7, the device can not get up and running as well. Under both systems, it is detected at the USB port, the same driver must be installed twice (otherwise errors in the device manager).
The program for reading provides no options, only a button for reading, but only the error message "Cyclotest not found" brings. The wars of problem-solving by manufacturer / program site.
Logically, since the hotline to transmit the data from the device and send the current cycle costs 10 euros per month. Here, the manufacturer wants to earn with poor software and drivers grottigen tidy.
What really on this device is missing, the Henkel is to throw away.
