Input: Consider Input: 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.

Output: Negative

Input: Consider Input: Because I remember loving and being absolutely terrified at these books when I was a kid, I recently purchased all 3 and just received them today. To my horror (and not in a good way) I found that they've published them with a DIFFERENT ILLUSTRATOR! With all due respect to Mr. Helmquist (the new guy) and certainly to Mr. Schwartz (the original author), these books were made for me by the art of Stephen Gammell. I'm sure they did this because so many parents tried to get the books banned in their day because of the ghastly drawings, but this is really a tragedy. I would suggest looking elsewhere for original copies of the books as they should be seen. Don't buy them here - you'll be missing out on part of what made these books so wonderful in the first place.

Output: Negative

Input: Consider Input: Can not beat this item for the price, hands down!Excellent product with all the features you could want, period.
