Great tool, minor quibbles
Very good, with a few rough edges. The ROI was clear within the first week of using it. A few missing integrations I'd like to see added. My team is very happy with the results.

Does what it promises and does it well. The interface is intuitive enough that I didn't need to read any docs. I've tried 5 similar tools and this one is clearly the best in class. Definitely worth trying.
