I've had the opportunity to work with Toluna a few times over the past years and it's always been a pleasure. The Quick Surveys platform is easy to use the the value for the money is terrific.
QuickSurveys was super easy to use and delivered results in a timely manor, which is very important in a fast moving industry like PR.
Super easy to set up, a lot of good options for survey questions.
No auto-sums -- led to dirty data that had to be manually cleaned. No randomization of answer orders.
The difficulty of getting a survey sometimes disturbs and discourages the user.
This was confusing though. The reporting and analystics of the surveys can cost more depending on what you want.
