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: I built my own \"charging station\" as every thing these days has a battery. This is the perfect little charging bar to tuck into the back of the valet. No more wires everywhere and no more hunting for chargers. The only reason I gave it 4 stars instead of 5 is the shipping time. It took almost 3 weeks to arrive. UPDATE 1/15/15 - I have had to replace 2 phones charged on this hub, one was a replacement for the first. I didn't realize until the second phone started acting up in the exact same manor that it was the USB. I downgrade from 4 stars to 1 (0 if I could)
