I like how you can make quick fixes for your site by simply creating an experiment with different variations of content or design elements in order to see which one performs better than others! The only thing about this tool i dislike would be its price point because it's very expensive compared to some free tools out there (like Google Analytics).
Try using it before spending too much money if possible as well; otherwise, try looking at alternatives such as GA. We were able to easily identify problems we had been having since our previous provider was no longer providing service and implementing solutions quickly so they could move onto something else.
