The user interface is very easy to use, it has all features that one could need for running an effective survey program with high quality results! I like how quickly you can get feedback from participants once they have completed their surveys - this makes managing my programs much easier than if i had no idea when people were completing them or even what answers are being given until after completion (which takes time). It would be nice to see more options available within each category so as not just limited by choosing between 5 responses per question but also having other choices such as "not applicable" which some questions may require. Also sometimes there isn't enough space at times allowing me to only choose 1 response out of 3 possible selections instead of 2; however these issues don’t seem too common nor do any affect overall satisfaction level since everything else works well otherwise.
