Accurate scale with potential for improvement

On the positive side:
+ The scale is very accurate. By that I mean that with repeated measurements in most cases even on point (0,1 kg) is accurate.
+ That you can export the data to Excel. Is also necessary if you want to view more than 30 records at a time.
+ Body fat measurement takes place up and down

What I did not like so much:
- Unfortunately, only 30 measurements per person can be saved.
- The fat measurement is very inaccurate - not really useful unless you calculate 14 days Durchschnittskurfen with Excel
- For rational analysis Excel is necessary. The export is really spartan. Normally you put in Excel with records for each record a new line. Here, each record has a new column (you can "copy - paste special - transpose" with correct but.
- The balance displays based on the BMI to a +/- bar. There illogical malfunctions. (Example: I take off easily, had suddenly on the beam but more overweight than before.) Noticed is this malfunction me only at certain weight ranges.
- The body fat indicator varies greatly despite the many measurement points, so no trend is visible in the display. Only when I each have a 14 day trend let calculate (mean value over the last 14 days) in Excel, it is a sensible line. Would be great if the scale would do so independently, since no statement can be derived from the individual measurements.
- The scale is not linkable with Beurer heart rate monitors.
- The balance is not suitable for small weights other helpful because only emanates from a certain minimum weight of a person and otherwise refused the display / measurement.
- The linking me to the PC does not always work smoothly. (Tip:. First, start the software - only then, plug the USB cable before the next person is read, it may be necessary to close the program - Stakeout - and restart - then reconnect with this approach but it worked.. )
- The keys go something hackelig and sometimes you have to press firmly to have a reaction. But then they work.
- Data Delete function can be hiding something.

Despite the many negative points I give the scale 3 stars because it is the basic function - to measure the weight accurately - performs well. Without this everything else would be worthless. Furthermore, I like that I can remember and read the data. In Excel I can easily watch the course of an entire year and analyze. With the - albeit self-programmed - Trend analysis (14 days average) I see how my muscle percentage increases eg during physical activity.
