[Q]: 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.
[A]: Negative

[Q]: All of the good things said about "Helter Skelter" is true of the Kindle edition. What's more the Kindle edition has hyperlinked footnotes that actually work and take you instantly to Bugliosi's notes. But the trade-off is that with the Kindle edition THERE ARE NO PICTURES because of licensing issues. The print edition has lots of pictures, but many of the crime-scene photo's are censored.
[A]: Positive

[Q]: This book is about colonel Knox a leader of a freshly starting revolution in America. His mission is to carry around 200 cannons from Ticonderoga back to a city where British forces are docked. The main characters of this book are will Knox 19 year old brother of the colonel, colonel Knox in charge of expedition, J.P. a farmers son .I disliked this book. It drags on and never seems to end. Just when you think your going to get a fight there isn't one .the biggest problem they had on the trip was a river with too thin ice. What's so interesting about that? If I were you I would not buy this book. It is extremely boring.From a reader of this book
