Given the task definition and input, reply with output. Given an Amazon review, indicate whether it is a 'Positive Review' or 'Negative Review'.

I bought one of these 7 months ago, and it started screeching really loud after about a month. It did that off and on, and then after 6 months it just stopped working completely! I took it back to Walmart today, and they miraculously let me trade it in for a new one without the receipt. It has a warranty on it, either one or two years depending on the model, so save all the info and the receipt if you already bought it, or if you are going to buy it (don't waste your money)!!! It WILL fail on you. I'm just counting the days until this next one breaks. Pros: It does a pretty good job cooling you laptop if your computer takes in air at the bottom. Cons: It's really loud sometimes, it breaks easily, it uses up a precious usb port, and it's wayyyyy too small for the bottom of my laptop, making my laptop wobble around on it.
