Given an Amazon review, indicate whether it is a 'Positive Review' or 'Negative Review'.

Example Input: I purchased this machine 4 months ago. This machine has to be one of the poorest constructed machines I have ever purchased. It only has one tiny little slot for the PCU fan (which clogs with dust) and has no way to open and dust it out. Now the fan is completely inoperable and the machine overheats and shuts down within about 20 minutes.
Example Output: Negative Review

Example Input: I got a kindle fire for Christmas last year and as soon as the warranty ran out my kindle battery stopped charging and then my kindle wouldn't turn on at all and what does Amazon do tell me that I can replace it for $127-$139. Sorry, but the kindle fire was $199 when my family got it for me and I do not think that I will pay over $100 to get it replaced, seeing as it stopped working through no fault of my own (I babied that thing). Needless to say that I will not be buying another kindle, I would rather save my money and buy an ipad because I know Apple will repair what they make.
Example Output: Negative Review

Example Input: the microphone did not work from the day i recieved it. I ordered this because of the great reviews it was getting. I now have a telex, USB digital microphone that is incredible, it was worth the money, so that is what i reccomend.
