Could you explain what you mean by 'no need to manually refresh'?
I understand this to mean you don't need to refresh your browser to see the changes you've made in your source.
EDIT: Ah, nevermind - just read up on it: "Our LiveReload watch process automatically compiles source files and refreshes your browser whenever a change is made so you don't have to."
I think people who spend huge amounts on diamonds are stupid, but everyone has their reasons.
