Detailed Instructions: In this task, 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.
Problem:I am so disappointed. We have several Rtic cups. We love them. I purchased the ones I currently have from the Rtic website. My husband lost his large tumbler and needed a new one ASAP as he uses his daily. I figured I would purchase one from Amazon so I could take advantage of my prime shipping. The reviews were great so I placed my order. My husband used his new tumbler for the first time tonight. He filled the cup to the top with ice and added water. Within an hour all the ice melted and the cup was cool. He had the lid on the whole time. Lesson learned. I’ll now be ordering straight from Rtic. I just wish I didn’t waste my money.
