Pros: Very slick interface. Easy to setup any survey. Survey's are best in mobile, but works great on a desktop too. I have ended up using more than I expected and can't think of any bugs, so it's well thought out. Customer support is top notch.

Cons: Only real con I can think is most of the updates that have been rolled out require a additional subscription. However, if you are a power user, probably worth it. I, however, am not sadly.

Summary: Great product & worth the investment. Highly recommended.
