In addition to survey results, filtering, and exporting, another feature of our reports is respondent comments.  For each survey you create you can view feedback the respondents had about the question itself, in addition to the answer they provided to the question.  On this page for each question that one or more respondents gave feedback, the feedback will be shown.  The respondent's name is never given with the comment so as to keep the responses unbiased. 
Benefits: Feedback is an invaluable resource in designing your next survey and allowing respondents to add comments about whether they thought the question was presented clearly, the answers were relevant, or any other feedback that can provide you with information on how to make the survey better in the future.
