The ease at which I can create dashboards quickly without having any coding knowledge has been amazing! Creating my own customizations is easy too so that it fits in perfectly amongst our other tools we use for reporting purposes (such as Tableau or PowerBI).
We are able to pull data from numerous sources into one view easily allowing us to see trends across multiple departments more effectively than ever before. It's not perfect - sometimes performance drops when working over larger sets of tables/data but this could just come down to how busy their servers get during peak times etc., maybe try using them if they're offering free trial? They've helped me solve many problems by giving access to large amounts of information within minutes instead weeks previously spent gathering through spreadsheets / manually looking up numbers online.
