I like how easy this was to install on my site. The analytics are great - especially the integration with Google Analytics. I like several of the extensions and the possibility of integrating chat with other applications. I like that they have free trial. The chat interface and its behavior are customizable to match our site's look and feel and business workflow. You can define the number of users and get billed based on the actual number of users. You can go up and down on the number of of users depending on your needs. Olark's customer service is helpful and responsive.
