How easy is it to create a questionnaire? Do they have a giant template library for you to browse through to create and edit surveys from? How about if you have a survey or questionnaire that you've already created and would like to import that directly into the editor? Do they give you the option of doing that? How about if you're just looking to create a survey from a blank template? What kind of options do you have? Is there a question bank of over 30 various question types to choose from? How about changing the look and feel of your survey? Can you browse through themes already made, or perhaps modify the CSS of the template?
With QuestionPro, you can do all do everything mentioned plus more!
