all information available

Step by step is explained everything well understood. The input of data is of course very expensive, but necessary. Then to work well with the WISO Hausveralter. For all inputs give it cross-references, where ambiguities can be disposed of safely.
The possibility of sample cases makes everything understandable.
The current PATH is also included = super.
There is always the internet connection the opportunity to consider whether updated versions are available.
For me it was the right choice in any case!
