In this task, you're given a review from Amazon's food products. Your task is to generate a rating for the product on a scale of 1-5 based on the review. The rating means 1: extremely poor, 2: poor, 3: neutral or mixed, 4: good, 5: extremely good. 

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 Input: I don't know how people could say this doesn't smell or taste bad. It is horrible!! I was getting raw goat's milk for quite a while and when we moved it wasn't available. The fresh raw milk was delicious and mild and did not have that gamey odor and flavor that this milk has. Maybe some people don't mind the taste, maybe some acquire a taste for it, and maybe some even like it, but I think it is vile. If you like the taste of the goat's milk cheese in stores, then you may like this, if not, stay far, far away!
Example Output: 1

Example Input: Okay, I admit it, I'm a red licorice junkie. But I don't care for Red Vines or Twizzlers; they just don't have the "tooth" I desire in a good whip. These spirals are very tasty (almost too good) and they offer a good, long chew. The one drawback is that they tend to be very oily thus the reason for my 3-star rating. Still the berry flavor is spot on. Just what I love about strawberry licorice. Warning: Having a 5 pound bag of licorice in the house will weaken even the mightiest willpower. You've had your caution.
