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: We have this model about a year now.  It hasn't worked right from the beginning.  We often had trouble closing the top.  Sometimes it doesn't work at all.  Other times it works like a charm.  When it works like a charm, it's not uncommon to find coffee grounds in the cup. It's a mess.  I bought the same model for the office. The experience was similar.  Sometimes it makes a full cup of coffee other times it doesn't.  Sometimes it won't even work at all.  We have to turn it on and off and cross our fingers. A friend reports these problems as well.  I agree with the reviewer who says, DO NOT BUY.  A waste of money for the machine,for the K-cup that couldn't be used, and an exercise in frustration. We're in the market for a different brand.  When Keurig first came out, they had the market.  They have a lot of competition now . . . which hopefully will make it easier to find a machine that works well.

Output: Negative


Input: Consider Input: We first had Stonewall Waffle Mix when we received it in a gift basket about a year and half ago.  We have been using it ever since.  The flavor of the waffles are absolutely out of this world.  We won't ever go back to Bisquick for our waffles!

Output: Positive


Input: Consider Input: 6-Hour Power's ingredients are pretty much the same as its rival, 5-Hour Energy's, so obviously the effect is pretty much the same. Yet, this cost me $18 for 12 while the other cost me $8 for 2 at the nearest store.  Great savings even if you only need these just a couple times a week.  The taste isn't as tangy and addictive as 5-Hour Energy's berry flavor. A bit bland in comparison, but it's still nowhere close to bad.


Output: Positive
