Input: Consider Input: I was extremely disappointed with the fabric and color when it came. It is obvious that it is of poor quality but I guess you get what you paid for 10 bucks.The zipper of the plastic cover of one set was broken.I bought 2 queen sheets and I wanted to return both purchases if only I did not have to pay for shipping.Do not buy this!!!! You will regret it.

Output: Negative

Input: Consider Input: I got these for my jawbone headset. Many had said they work great. but for the life of me i cant figure out how you get them to work short of superglue and even then they are too quiet to hear so i guess they work on the jabra they are designed for but not the jawbone.

Output: Negative

Input: Consider Input: This book was a bit more difficult to follow, in my opinion. I was lost toward the end. But Patrica is an awesome writer! I'm sure the problem was me, not her writing.
Output: Positive
