We use assess for creating surveys that are distributed internally as well out in our market. The features like auto-completion of questions makes it easier than ever before! I cannot think any weaknesses at this time because there aren't many things one can dislike about their product (and even if they did exist - which we don't have). If you want an easy system, with all functions needed under 1 roof then definitely give them try. It was not possible earlier when using multiple 3rd party tools such as Survey Monkey or Google Forms etc., due to compatibility issues between different versions; hence the need for more robust software came into play.
