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

Input: Consider Input: First, the shipping took forever but I was willing to overlook that seeing as how I didn't need it immediately. After I received the battery I conditioned it (let it charge and discharge fully a few times)and it was working fine; held a charge for around an hour forty-five to two hours. A week or two later I noticed it wouldn't charge past 17%, another couple of days and I can't unplug my laptop without it shutting off. First time I bought from the seller so I don't know if I just got a bad battery or if the seller's products are faulty to begin with. I will be looking into returning.

Output: Negative Review

Input: Consider Input: I was looking for a slender case for my Kindle (my current one is secure and padded but bulky) when I came across this offering. I've had flip top cases for old-school PDAs in the past and thought that would work fine. I received the case and it looked great. I put the Kindle in and within an hour was feeling mildly woozy. Soon after, I realized my scratchy throat and watering eyes coincided precisely with using the new case. It has a potent chemical smell. I don't know if it originates from the case's materials or the adhesives used to assemble it. I tried various methods of \"airing out\" the off-gassing case but after a few weeks realized that it was never going to work. Simply being in the same room with it made me sick. I finally pitched it in the dumpster, which proved to be the smartest move. Haven't felt ill since...

Input: Consider Input: This product worked great for a few months and then all of a sudden stopped. I didn't realize I was going to have to keep buying and replacing this unit. I supposed I should have just spent the money on one made by Apple. THis unit gave my computer power and did charge it too. A little while after I got it, it just started giving my computer power, but not charging it. Now it doesn't do anything. I guess it was too good to be true. i was excited at first that it worked, but now I feel like a sucker. Save your money and your time and just get ONE that will work for longer than a few months. That's ridiculous!!!!
