The thing with vendor dependent forums is that people only visit them when they have a problem.... This makes it allways look far worse then it actually is..
Also with the Wersi being a software based instrument never run the latest software version if not necessary at all.....so when they do major updates just wayt a few months, sson they might go from 7.1 to 7.2 versions ... I wouldn't do such an update without having decent feedback from early addaptors.
Next to that Many people upgrade their hardware themselves....oh so many problems come from this.... ESD anyone?
Baing based on windows and software most people start exploring and toying with it... and do things they should not do as its not good for stabillity...

The problem with people wayting on Wersi parts i never got, because the people i know from the internet that have a wersi have never needed to wayt long if wersi had the parts in stock and they decided to get a new part..
