Example 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.
Example Output: Negative
