Instruct: Classify Amazon reviews into positive or negative sentiment
Query: READ REVIEWS!!!

This product is a prime example of why you should always hop on Amazon and check reviews of products before even running to Walmart and buying something. I'm sitting here trying to burn some DVDs and a good half of these DVDs won't burn. I hopped on here to see if other people have the same problem with this product and sure enough. Look at the reviews. Now I have to do some research and pick up another brand to get the job done right.I knew to check reviews, but had the impression that Memorex was a good brand. Lesson learned that I thought I already knew.
