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 two bags of these, thinking it was the same product that I used to buy in different packaging (light blue, with a see-through dog shape against a grass green background). Unfortunately, it was completely not the same thing! These treats were actually like jerky-- tough and brittle. I give my dog soft treats because he doesn't chew the damn things, and he choked on these horrible things; I had to toss them out. Note that the "Zuke's Jerky Naturals" with the other packaging (http://www.amazon.com/Zukes-Jerky-Naturals-Beef/dp/B00008DFPY) have always been moist and soft, and I've never had a problem with those. I suspect that this batch was not new packaging, as I had thought, but very old packaging; these may be the same treats I usually feed my dog, just having sat on a shelf for years. In any case, these were COMPLETELY different treats, and not safe to feed my dog.

Example Input: I had read some favorable reviews of this pancake mix on Amazon quite a while ago. I had never ordered any, but I came across a can of it in one of those outdoor,camping stores last Christmas. I have been using it ever since to make my dieting harder, and can honestly say I have never enjoyed the struggle so much. Pancake mixes are usually one of those things that usually I buy the cheapest I can find, or at least one that I am familiar with. I tend to balk at higher priced mixes for the most part. But every now and then I get curious of a brand like this one. It just so happens that when I visited this camping store, I was getting ready to take a short hike as soon as the holidays were over, and pancake mix has always been one of my staple items to take along. Unfortunately it wasn't 'till I left that I realized that this mix was not one of the "just add water" ones that we all know and love. The best ones always needed your own addition of eggs, milk, butter, etc, and this one is no exception in that respect. So instead of enjoying this mix on the trail, I have been making pancakes in the wilds of my very own kitchen. I really don't know what it is about this mix that makes it so good, but it does indeed make some of the best and most delicious pancakes I have ever tasted from a mix. They are very light, fluffy, and flavorful, and well worth the price and ingredients that you have to add yourself. If you have a pancake fiend in your home, I would highly suggest you buy some of this great mix. Its cheaper here on Amazon than I paid for it and well worth it in my opinion. I have had lots of different kinds over the years, and this makes some truly delicious pancakes.... Highly recommended...
