Teacher: Given an Amazon review, indicate whether it is a 'Positive Review' or 'Negative Review'.
Teacher: Now, understand the problem? If you are still confused, see the following 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.
Solution: Positive Review
Reason: This rating is correct based on this review provided by the user as they liked the product very much and they were surprised that product is so good.

Now, solve this instance: This product worked great for a few months and then all of a sudden stopped. I didn't realize I was going to have to keep buying and replacing this unit. I supposed I should have just spent the money on one made by Apple. THis unit gave my computer power and did charge it too. A little while after I got it, it just started giving my computer power, but not charging it. Now it doesn't do anything. I guess it was too good to be true. i was excited at first that it worked, but now I feel like a sucker. Save your money and your time and just get ONE that will work for longer than a few months. That's ridiculous!!!!
