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

Example Input: Trackball feels as though its running with occasional grains of sand. Esc Key needed to \"get things going\" on first use. Key 7 fell out and seems to be partially broken as it won't clip back in as securely as the other keys. Rubber trim and foot fell off. This keyboard is slowly coming apart
Example Output: Negative Review

Example Input: Really wasn't sure about getting a Kindle because I love real books, but this has really converted me. I had stopped reading because I like to jump between one or two books, and I got into the habit of always being on my phone while in waiting rooms. :( It made me realize how much I miss reading magazines or a novel, but I'd hate to carry two novels. Got this baby on sale, and works like a breeze. Lasts for days without being charged and I don't get distracted with notifications like I would on an iPad.
Example Output: Positive Review

Example Input: I am completely happy with this phone, good sound quality, in base and remote. Very user friendly.
