What am I reviewing here... this gizmo or the supplier, Eforcity? I never received this product after my order! After waiting and waiting I contacted Eforcity several times -- no reply. After a nasty letter from me Eforcity'r reply feigned lacking information about my mailing address!What a cop-out.I told them I would not pay for it, so Eforcity said they'd give me a refund, which has not come to me yet. I bought another product to replace this from Amazon which arrived quickly from Amazon.

Ex Output:
Negative

I think beyond the fact that Hazlitt produces a succinct and well-argued explanation for why free markets are the best arrangements in economic relationships, what is really wonderful is reading the screeds of those readers that he pisses off! Read the rabid ranting temper tantrum of the one reader who amazingly was accepted to the University of Chicago and you can see how ideas that actually support free thought and productive profitable endeavors drive lunatics like this crazy - its awesome!! This dork probably marches against the WTO.

Ex Output:
Positive


Ex Input:
The synopsis of this book sounded spectacular, a conspiring journalist gets stuck on a utopian island. The book starts off kind of entertaining but with a bit of rambling but you figure as you go on, it will probably subside. It doesn't. The characters keep going on and on about buddhism, sex and mushrooms. The plot barely starts and barely ends. This is a book with no journey and no destination.

Ex Output:

Negative
