Instruct: Classify Amazon reviews into positive or negative sentiment
Query: First time buyer

I was a little nervous purchasing books on-line, but after reading previous reviews from other buyers, I took my chances. I could not believe the impeccable condition of the book purchased. I recommended this to my co-workers and I want to thank the seller and past buyers (on their reviews) for such honesty. Such a pleasure to see this quality still being effective. Thanks.
