It's easy for us as we are not data scientists, but it does what its supposed too - give you all kinds of insights into your business! I wish they would add more features (like custom formulas) so that our team can use them without me having an account there myself.
We do have other tools like Google Sheets or Excel where this isn't really needed in many cases though- just keep using those if thats sufficient enough :) If anyone wants insight about how their product works/what kind analytics information etc., check out pricegrid first before buying anything else from another provider because i think even big companies struggle with giving good answers here sometimes ;).
