Example Input: I used to have a hello kitty usb flash drive like this one and it was great. I never had a problem with it and then I misplaced it. So I bought this one because it is super cute. I haven't even had it for more than 2 weeks and it gets hot. I constantly have to take it out of my laptop because I get pop ups that say my flash drive has malfunctioned. The head even melted off of it. I'm so upset about this and for some reason there's not an exchange or return option on here for this product. If I could get a replacement and it work properly, I would happily change my review. Because for the first week it worked great, but after a couple more weeks it's basically trash now and I will have to purchase a new one somewhere else.
Example Output:
negative
