Given the task definition, example input & output, solve the new input case.
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: I have bought several of the Vitality canned dog food products and have found them all to be of good quality. The product looks more like a stew than a processed meat and it smells better. My Labrador is finicky and she appreciates this product better than most.
Output: 5
The user really seem very satisfied with the product and gave good review worthy of 5 stars rating.

New input case for you: This is a really easy way to make terrible iced tea. Sometimes convenience outweighs taste, but not always. What this product doesn't tell you before you buy it is that the ingredients are: black tea with tea extract, hibiscus and citric acid. It's not just tea. And it doesn't taste like just tea, either. It tastes like powdered iced tea from a jar. It has an overtaste of lemon -- that's probably the citric acid. And that fake tea flavor that comes from powdered iced tea mix. I'll probably drink it when it's really convenient. But I won't serve it to friends! And I won't drink it if I have time to make a glass of real tea and pour it over ice.
