We used it mainly for ETL but also some simple SQL statements were created with this tool as well! Easy enough use if need be; we could get by using just an excel sheet instead so there's no point really complaining about how easy/difficult something was (if anything). I dislike having multiple tabs open when working because my PC doesn't like them very much - they can slow down over time etc which makes finding things hard sometimes too since everything gets crowded up together. Good product though overall even after our project finished due to lack funding issues in terms of resources needed from other staff members who helped us out during testing / development phase.
