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.

Input: Consider Input: I bought this for my elderly parents who seem to struggle with the use of almost any technology. So far, they have been able to use this in their own with minimal intervention from me (which is greatly appreciated)

Output: positive


Input: Consider Input: This item does not heat despite being turned on. In addition, the rack was nearly impossible to put together to be free standing. The provided screws were too big for the holes. Terrible product! To top it off it had absolutely no instruction on how to put together as freestanding.

Output: negative


Input: Consider Input: I went to one of our local dental clinics last month and was suggested to spend around 2 hundred dollars to get my teeth molded through them for a mouth guard, but I said Thanks! NO! it is not affordable for me! Surprisingly I found this Phoebe mouth guard for my grinding teeth, which can save me a lot of money, and to be honest I did not have high expectation in the beginning but the price is so good for me then I decided to have a try, and never thought it could work so well to stop the damage from teeth fringing! Here are some tips of what I have done as below: 1. Drop the mouth guard into the hot water. (one piece at a time), and just lightly hot warm water. 2. Use a wooden spoon to scoop the guard in the hot water and shake off all hot water. 3. Grab the guard and place it on the row of teeth you are molding. Use the indention in the center of the guard to line it up with the center of your row of teeth. 4. Once it is in your mouth, close your mouth and begin to suck in--almost as if there is food stuck on your teeth that you're trying to remove without a toothpick. Also, while you're doing that, press down your lips towards your teeth to give it an extra help to mold to the front of your teeth. Use your tongue to get inside in place. 5. Keep the guard in your mouth until you feel it firm up. It'll probably take a minute or so to set. In addition, there are 3 packs with optional sizes to choose from, it was slightly tricky to get it to perfectly set comfortably on my teeth. But that is fine--if you don't get it the first time you can always try to reset it by dunking the pieces back into the hot water. By the 2nd (or 3rd) it should be pretty easy to get it exactly the way you want to be.
