The user interface is very simple to use which allows me as an analyst who has limited experience using this tool do my job faster than before without any help from anyone else in our team or other third party resources like consultants etc.. I also love how fast they are at responding when we have questions about their product! It would be great if there was more customization options available such that users can personalize its look & feel according too what suits them best but overall i am satisfied by all aspects of Atlas ti so far!!
