In this task, You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.

Example Input: After the third use it did not charge up any more. Ok if you want a disposable charger to throw away after only a couple of uses. It worked ok for the three times that I was able to use it. However it did not charge my phone to 100%, only to 80% before it lost all of its charging power. I did not have a problem plugging it in to my Pixel 3 with a case on it. But that doesn't matter now as the charger does not work. Seriously, do not purchase this product. Other one star reviews can attest to the same fault.
Example Output: negative

Example Input: Not water tight...? moisture inside lenses after only a couple weeks of installed use. Was sent replacement, and it did the same after only a couple weeks. Then after about 4 months half of the lights stopped working.
Example Output: negative

Example Input: This is my second filler, I had to return the first one that was a little cheaper as the instructions were gibberish which made it nearly impossible to figure the process out by myself, it also didn’t have this white thing to stop the powder from falling off which made it VERY messy and wasteful and most importantly the product felt cheap and destroyed most of my capsules. This one however was a couple of bucks more, but you get what you pay for! Great instructions, powder spill block included made it WAY less messy and above all great quality. I had 100% success my first time. Happy with my purchase
Example Output:
positive
