This software has helped us to analyze our website traffic, which was not visible in any other analytics tool we used before this one! The cost factor makes it difficult to use log analysis feature at times when you need some help with your business problems fast. But I guess that will change over time as well once they have more clients who are willing pay them for their services. We didn't really experience anything negative yet but then again if there's nothing to dislike about such powerful product surely all good things come together eventually. Try using its free trial version first so that you can get yourself familiarized with how everything works here. It does provide many useful features within few clicks. Our team uses these tools daily during work hours along with Google Analytics (free) and Bing Webmaster Tools(Free).
