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: Either I got 15 tubes that came from a bad batch lot or they are not selling the right Harissa. I bought 15 tubes thru Amazon from Parthenon Foods and used 4 of them so far and after putting the whole tube it still isn't spicy at all. Normally a whole tube would get you to sweat a bit!!!!! This seems to be a case of false representation. I buy these tubes in Canada at the grocery store all the time when I am up there and they provide a nice kick and spice (as they should). What's up with dat?
Example Output: Negative

Example Input: I normally bake from scratch but when I saw this pink lemonade cake mix with matching frosting I just had to try them both. This cake can be made two ways: with or without egg yolks. I recommend with as the cake will be nice and moist as a result. This cake would also be just as good with plain white icing or just a dusting of powdered sugar. You can make it as a layer, bundt, or sheet cake, or as cupcakes. I picked it up at the grocery store recently for about $1.80 per box, the frosting was about the same price per can. I ended up going back and purchasing more for later as I believe this is just a seasonal flavor and Pillsbury will pull it from the market at some point. If they do I hope they bring it back every spring. Until then I'll be stocking up.
Example Output: Positive

Example Input: I ordered the ener g brand because that is the brand of bread we had a Disney and the kids (and one adult celiac) were very excited about everything they had there.  These brownies do not measure up to the bread that ener g makes.  I've never met a brownie I didn't like but I couldn't eat it (even with ice cream).  The clear sign was when I had to throw some away.  They will eat them if they are desperate for something gluten free.  Anyone who has been dealing with gluten free products probably already knows to freeze the items until you get ready to use them.  They mold quickly.
Example Output:
Negative
