I like that it can be used for any website or application where you need to track users' behavior (eCommerce sites).
It's easy enough so anyone who has basic HTML knowledge could use this tool without much trouble at all! There are some features which seem too advanced/complex but aren't actually as complicated when put into practice - they just require learning how each feature works in order make sense of them later down the line if needed :) Definitely try out their free trial first before buying; there is no risk involved because once purchased we have access forever unless cancelled via email within 14 days from purchase date!! We're using fly primarily through our ecommerce site monitoring user behaviour & improving conversion rates by understanding what actions people take after viewing products etc., however other areas such us customer service surveys were also implemented successfully here.
