Example: I was very surprised at the high quality of the stitching, the sturdiness of the handles and the padding for my laptop. The price is amazingly low and the look is very good. I am quite happy with this purchase. It fit my MacBook Pro perfectly, with a little bit of room to spare.
Output: Positive Review

New input case for you: First system would not power up so returned it to Amazon ... replacement arrived the next day. Second system could not establish communications through coax. Spent 2 hours going through online documentation and troubleshooting instructions, then called tech support. ... Spent more than two hours on the phone over two sessions with 4 service reps (all based in India) before being transfered to \"Senior Technician\". The Sr. Tech spent 20 minutes determining I needed to go to Level II support who was based in Manila. Finally got resolution 20 minutes later ... return the defective units.
Output:
Negative Review
