The tool is very easy for me as an analyst who has limited experience with GIS software or databases in general because it's intuitively designed so I can quickly find what information i'm looking at without having too much of my time wasted searching through menus etc.. It also allows you to save your work into different formats which helps if something goes wrong (like when saving rasters). There are some issues like not being able to select multiple layers but this doesn't really bother us since we're only using one layer anyway! Great interface overall though - nothing bad about how they've put everything together- just minor things here & there such as selecting more than 1 file/layer would be nice :) Highly recommended especially considering its free version offers all features including 3D models!!
