I think it was our GetFeedback sales rep who used the PowerPoint analogy to us when first showing us the survey builder. It really is so easy to build a professional looking survey that I've put the app in the hands of two completely untrained staff members and their surveys came out looking just as good as anything I've ever built in the past! Since all the surveys are completely mobile friendly without any additional setup needed, this ensures that as our customers shift more and more to mobile devices for emails, that when they launch our survey link on the mobile they will hopefully follow through with completing it too!
Other than simplicity of use, Salesforce integration was another feature that narrowed down GetFeedback as being one of our possible vendors. Their integration is easy and was setup completely in house by a Jr. Admin in a matter of only hours. There's also a lot of flexibility with the integration in regards to where survey results can be stored in Salesforce, and since we use a lot of custom objects this flexibility was very important for us.
Don't let the simple GUI fool you though, because GetFeedback does have a lot of power to harness too. We've leveraged it's branching logic builder to build some very dynamic surveys that take a user through different orders of questions, excluding ones that aren't relevant, all based on the product they have in Salesforce that is pushed through into the survey. In some competing products we would have had to build unique surveys for each product, and this would have been an inefficient use of time for our small and nimble admin team.
Sometimes it's <too> simple and we find ourselves wanting just a little more customization on the survey pages, such as the ability to have two questions on a page (if questions without long answer areas), or the ability to control font size/styling. On the flip side, I also understand them forcing users down a fairly standardized format for surveys because this does help ensure optimal mobile compatibility, which may not be as ideal if users can customize too much of the display elements.
As we continue to leverage GetFeedback more and more, we're finding ways to leverage it for the obvious customer feedback, like CSAT and Net Promoter scores, but we're also leveraging it in some more advanced ways to send information gathering surveys that cuts down on agent time and reduces data input errors by allowing the customer to directly provide information we need in various scenarios.
