There is a great review here, that unfortunately I read it after buying this.
but this has no support, and for me the main problem was that whenever I needed to add a lead it asked me to ADD AN USER.

THE problem the user was added, but could never configured because there was an error "could not send email due to SMTP" not setup. which i think it's their server problem, as there was no way for me to setup my own smtp here.
