I cannot praise this product enough, the simplicity, the detailed and complex features and options and the finished product, absolutely fantastic.
I highly recommend this product, the software itself is great, easy to use and gives a great survey experience.
We used this for a rapidly implemented survey. It was excellent - easy to set up, and the analytics in the Professional option are really very good and allowed for frequent non-expert review.
To do one particular function it used to prompt me to upgrade my membership which in my view proved costly for me.
It took me a but to figure it out. That might be a user error on my part, nothing wrong with the software.
Maybe make that more obvious. But that is just me as I used it only for 4 months every year, so from year to year, I forget.
