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.

[EX Q]: 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.
[EX A]: Negative

[EX Q]: I am the biggest fan of mushrooms you'll ever meet, but these are really disgusting. They taste like dirt. I have to imagine better quality truffles (if these are even truffles at all) are muuuuch better. They'd have to be. There'd be no comparison. These are really bad.
[EX A]: Negative

[EX Q]: The folks at Starbucks are not exaggerating when they say their French Roast coffee is "Extra Bold."  In fact, they should probably call it `Extremely Bold'...or maybe even `Ridiculously Bold.'  The directions on the package recommend 2 tablespoons of coffee for every 6 ounces of filtered water.  The result is likely to disintegrate your ceramic mug before you can drink it, but it doesn't taste too bad...that is until the bitter aftertaste kicks in and makes your throat burn.  If you weaken it by adding some hot water, as the package suggests, the bitter taste becomes more pronounced, like coffee that's been left heating in the pot too long.  The only way to drink this coffee is with plenty of cream and sugar.  With enough cream and sugar, French Roast is pretty good; but I wouldn't recommend this particular Starbucks variety if you like your coffee black...unless you wanna stay awake for a week.
