I like that it allows me to create dynamic reports without having too much coding knowledge, also allowing you can use your own data sources if needed (which is not possible with other tools). It's free but there are some limitations when compared against more expensive products - for example only up-to 10 tables in one report or using multiple databases at once as opposed of just 1 database which limits its flexibility sometimes; however this limitation could be solved by paying extra fees so maybe they should consider adding paid plans instead! The UI/UX layout needs improvement though since most customers may find themself confused while navigating through their toolbars etc.; Also creating charts from scratch seems difficult because we cannot drag&drop elements such us pie chart into our dashboard easily either via web browser interface nor mobile apps due lack customization options out of box features provided within querytree itself i think? We used QTREE mainly during project planning stage where users need something simple yet.
