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: Much quieter than the default 3-pin fan that would spin at 100% all the time. Was a little shocked to find that the sides of the fan were a heavy/hard plastic and not rubber. The included rubber nubs that dampen the noise didn't quite work as I'd hoped thanks to Corsair's ideology of putting rubber grommets on all of the screw holes.<br /><br />Plenty of length on the cable (4 pin PWM) so it could reach the middle of my ASROCK Z97 Anniversary board's 4pin header and is now running at a smooth 35% speed at idle and 45% under load when the temps hit over 50C.<br /><br />Keeps the fan branding uniform throughout the front and back panels of my case (I have some Spectre Pro PWM LED's in the front) and is stealthed thanks to the black on black color scheme.
