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.

Example Input: I got these cocoa cups based on my sister-in-law's recommendation.  It has a great flavor and is inexpensive.  Quite a good combination.  I'll be ordering more very soon.
Example Output: Positive

Example Input: I have older mats that have a ribbed surface and work great. These have small stiff points and actually hurt to lean on or kneel on. I can imagine that they hurt my cats paws ad that is why they tend to jump over them when exiting the littler box.
Example Output: Negative

Example Input: I bought the Blue Icicle because I had to quickly record some trumpet lines and I didn't have an interface. Well, actually, I did pick up an open box unit that didn't work because they couldn't provide me with the external power supply, so I took it back and got the Icicle as a quick fix that would get me where I needed to go in a timely manner.  Hardware: iMac, dual core 2.0 GHz processor and 4 GB or RAM. OS 10.5.8. Software: Garage Band. Mic: Shure SM57.  Pros. For recording trumpet with an SM57 it was perfect. Clear sound, low noise, LOTS of signal. With the gain a little over half way on the Icicle and about 58% in Garage Band I got hot horn lines with gain to spare.  Any hotter and they would have started clipping, so it definitely gave enough signal to get the job done.  Cons. The gain knob has no dial or indicators for how far you have turned it - it has to be done by feel making it almost impossible to duplicate your settings exactly. This could be improved with a knob with an arrow and a marked dial so you can see where it's set. It also feels a bit cheap - it's lightweight and feels almost fragile. Treated with care it's fine, but I doubt it would take much abuse before it would break and I have been ultra careful with it because it feels so lightweight and cheap.  I also used it as recommended in the accompanying literature and didn't plug it directly into the back of the mic - I used it with a mic cable.  For what I needed it was perfect - simple plug and play that got good sound into my computer, and it worked well in a pinch.  I just wish it was a little higher quality in terms of construction.  A bit heavier and a better dial for the analog gain, and I would have rated it a full 5 stars but as it is, I can at best give it 4.
Example Output:
Positive
