 RecommendedPros: 

Innovative and approach towards CRM, simple in its nature and idea, cold mailing features

Cons: 

CRM based on Google Apps has its limitations.

If Google Apps / GMail is enough for you, this is a great extension, adding CRM elements to the tools you're already using on a daily basis.
