Example Input: My 4-year old girl loved the costume but unfortunately it did not include the mask. I inquired the seller and they confirmed there was a confusion : the description of the Costume did not include a mask , I replied even I did not notice it in the description, the picture showed the girl with the mask and there was no clarification about it. I think they should have made a clarification, it seems to me it is false publicity. It is good to know they have updated the picture.
Example Output: Positive

Example Input: Excellent product. I was having difficulty hearing and also getting a comfottable fit with the included ear hook that came with my Jabra JX-10 Series II Bluetooth headset. I removed the hook and attached one of the 6 gels that came in the pack to the headset and found that the volume increased 40% and I was able to achieve a comfortable fit. The headset is small enough and light enough that the gel holds the headset in the ear. I was about to give up on this headset (and all earhook type Bluetooth headsets) prior to getting the gels. If you are looking for a comfortable (and econimical) alternative for earhook type headsets, I strongly recommend that you give these a try. They are well worth the price.
Example Output: Positive

Example Input: This is a fantastic life after death experience written by a physician, whose credentials give greater weight to his testimony. He leads up to this miraculous event by recounting his life experiences, a bit of biography. I thoroughly enjoyed this book and it encouraged me tremendously after the recent death of my son, who had also proclaimed his faith in Christ before God took him. I enjoyed the book so much, I read it twice.
Example Output:
Positive
