Stay clear. First survey no issues. 2nd survey everything appeared fine although a lot of options were tied into very pricey upgrades. Then when closing survey, they suddenly tell you that you can only see /get first 25 responses. If I wanted to see others I would have to pay a heavy fee. So found a workaround - extracted info for first 25, deleted these and continued until all responses collected. 3rd survey: found the same issue but this time they said I reached the limit for deleting responses in my last survey (although no limit was ever mentioned in that one) so couldn’t delete any in this one without having to pay heavy upgrade fee! And funnily they seemed to set the limit of deleted records as the exact same number that I deleted from survey 2 - obviously tracking. They’re desperately looking for any way in which to charge you. Stay clear utterly useless and waste of time.
