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

Example Input: Very Junky, do NOT BUY!
Example Output: Negative Review

Example Input: After 3 months it was trash. Good thing I kept my original Sony battery of 5 years, which I had to put back as it keeps more charge than this 3 month old battery. Buy OEM, don't waste your money.
Example Output: Negative Review

Example Input: This cover is perfect. The leather exterior has a rich feel to it and I love the steel blue color. I also like the soft interior. It makes holding the Kindle very pleasant and also protects the all important screen when you are carting your KIndle around. I think the way the light fits into the back of the cover is awesome. I take my kindle with me everywhere and just pull it out to turn a frustrating wait into a pleasant reading break. The case is the perfect package, attractive, well-designed and makes your Kindle ready to read in the light or dark. I purchased mine from the Amazon Outlet store and got a great price on it. The only downside was that there were no instructions but it was easy to figure everything out with one small exception which caused me some concern. It was pretty stupid of me but I almost returned mine shortly after it arrived because I thought it wasn't working properly. I would pull the light out of its recessed position in the back cover and sometimes it would come on and sometimes it wouldn't. This made me sad because I was so pleased with the cover that I really didn't want to return it. I was sharing my problem with my spouse and we realized there was a click when i pulled the light out. We quickly figured out that you have to pull the light out until you hear that click or the light doesn't come on. I haven't seen anyone else with this problem and I don't know if it was covered in the instructions but thought I would share just in case anyone else had the same problem. Once I figured it out, i felt pretty stupid for not figuring it out immediately. All in all this is an awesome product and I highly recommend it for every Kindle owner. It keeps your Kindle safe and provides a comfortable and, when necessary, well-lit reading experience.
