do not need any prior specific knowledge

From the word go the online technical assistant is there to address any questions. The interface for the survey was also splendid and made people want to participate. The display of results on one page is great to give an overall impression in a short time

I love the stability of having my survey running for several years with no interruptions, unexpected changes, or crazy unexplained misfortunate events. The feature set is full and even the free plan is functional to get the job done.
