Review on Mach5 Analyzer by Jason Arkin

I like that it's easy to use, has all of the tools you need for analyzing your data (including graphs), and can be used in conjunction with other products such as Google Analytics or Omniture. It also allows me to keep my own custom reports separate from those provided by these companies, which helps when comparing them against one another. Some features are missing - e.g., some metrics aren't available for every site/page view. Also, there isn't an option to export the raw data so that it can be easily imported elsewhere if needed. We're using this product at work primarily to track customer traffic flow through our website.
