The best thing about this tool is that it helps to track all changes made in sharepoint sites so easily, Also you can get updates of your changed records automatically which saves time from manual checking or searching through them manually.
It sometimes gets slow during large file operations like uploading big files etc., Sometimes I have faced issues when trying to upload huge amount documents at once but i believe its because of my internet connection speed as well. Great feature if used correctly with proper planning would be great otherwise will disappoint you after using it! Tracking site content changes very efficiently without much effort.
