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.

Let me give you an example: These are junk! Both bulbs have burned out within a two month period!! I cannot believe that this company can be in business with such poor quality. I have used infrared lights for my ball python for many years now and I get a varied range of months from a bulb, but I have never gone through two bulbs in a matter of two months! I am very disappointed.
The answer to this example can be: negative
Here is why: The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, it's a negative review.

Update: I will NEVER BUY A CUISINART PRODUCT AGAIN, ever. Was on phone with customer service for an hour having to literally ARGUE with an agent -- who refused for a long time to transfer me to a supervisor -- and then with a supervisor. After all that, no resolution. All they offered to do was pick up the machine and send it for repairs...but we'd have to stay home, waiting for pick-up, for a 2-3 day period -- which could not even be scheduled for a particular week. (We're leaving for vacation in a couple of days.) Or -- get this! -- they'd email us a shipping label so we could take the machine to UPS at our convenience, but it would take them 2-3 DAYS TO SEND THE EMAIL. An email! After that it would be about a month before we got the machine back. Utter absurdity. **** Like many other reviewers here, I've bought this machine twice -- the first one was good for a couple of years (not as long as I'd expect from this brand), then started pouring water out the bottom instead of through the coffee basket, so I figured I'd just gotten a bit of a dud or the problem was somehow my fault, and I bought a new one. The new one is truly awful -- sounds like a combine harvester, and now, after just 5 months, it makes nothing but sludge with black crema and a half-inch of grounds on the bottom of a weak, bad-tasting cup of coffee. I've cleaned and re-settled all the external parts every way I can think of, to no avail. I'd expect better of a machine that cost half of much. Cuisinart used to make top-quality products....
