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]: If you're a fan of full-bodied coffees, give this one a shot.  For my taste, the vast majority of k-cups are too watery and weak (even on the small cup setting), so I gravitate towards the extra-bold varieties.  I had previously been enjoying Newman's Own Extra Bold and GM Dark Magic.  After reading some favorable comparisons between those and Mahogany, I decided to give it a chance.  I find that it's slightly less bitter (not that bitter is bad) than Newman's EB or Dark Magic, and a little smoother.  I also think it's more full bodied without any burned bean flavor.  I've tried the Mahogany on the larger cup setting and actually still liked it -- something I've never said before.
[EX A]: Positive

[EX Q]: Kettle chips are thicker and crunchier (though greasier at times) than other chips, and the honey dijon flavor is great.  They don't have the overwhelming salty taste some cheaper chips have, and the 2oz size is great for an adult size snack.
[EX A]:
Positive
