A unique and brilliant approach to surveys and results

I have been using WP Forms which has a great ui for creating forms, however it is expensive and does not deliver results to users and in a collated way. The Modal Survey is brilliant as you can use categories for a questions or even better answers and then produce charts for those categories. This gives very meaningful results and there is flexibility on how those results are delivered… QSM also uses categories, however collation is currently not yet available and the costing is not int he same league as Modal Survey at this time.
Pantherius has produced such a powerful plugin with such flexibility and realtime reporting to the participant as well as cumulative.
The support has been responsive…
What 4 stars? there are as with all plugins some features which would further improve it eg 1. True Likert Scale/Grid approach using groups of answers 2. More control over the pdf attachment content to the participant… however the shortcode options are amazing and I recommend this plugin…. it takes a bit of learning… however it is worth it. ??
