Feature points?

Hey guys has anyone tried Feature Points and know what kind of conversions i could expect?

I've been using MyLikes and Amazon affiliates to make money from tumblr and thats been alright - about $400 a month - but im looking for any better sites. My blog is science based btw, if that helps.

I've used Feature Points for a few months and it's been awesome! I've made a few hundred dollars in a short period of time.
