So here is what I got :-
It helped my blog reach 512ec/day price for a 125x125 ad on Entrecard widget. Though the price is not same at present or may be same if you check but it really helped me cover those 750ec easily which I spent on buying Featured Status.
Moreover it also helped me improve my blog's popularity rating which I think was impossible for me if didn't used Featured Status.
What I Recommend
Featured Status is really worth it.. A must buy item for bloggers at Entrecard!
