Instructions: In this task, you're given a review from Amazon. 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, 4: good, 5: extremely good.
Input: The bad: it is very hard to get the hang of using this thing. I have to try to get it on my lips at least 3-4 times each time I use it before I finally get enough suction to plump my lips. The instructions that come with it are inadequate. I googled how to use similar products and watched you tube videos. Also, it is pretty uncomfortable once you get a good suction. I have a pretty high pain tolerance so I can stand it for a couple minutes. Now for the good: It does work. My lips stay plumped for about 2-3 hours. I wanted to see what I would look like if I got injections and now I know. I have not bruised at all like some of the other reviews have said. Overall, I'm happy I bought it.
