Easy form creation process for both administrators as well end-users who are filling in their own information without having technical support nearby! It has been so easy that we have used it internally at my previous employer (where I worked from home) instead of creating an internal website/app just because everyone had access to computers but no ability create content themselves.
There's nothing about this software which really makes me dislike anything specifically - other than maybe how expensive some features cost compared to competitors products like SurveyMonkey etc., however these costs do add up over time if you're not careful. We use Turboparts extensively within our organization; whether its surveys, questionnaires, quizzes, polls, signups, registrations ect.; they all work great together seamlessly when combined into one platform.
