Given the task definition, example input & output, solve the new input case.
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.
Example: These are junk! Both bulbs have burned out within a two month period!! I cannot believe that this company can be in business with such poor quality. I have used infrared lights for my ball python for many years now and I get a varied range of months from a bulb, but I have never gone through two bulbs in a matter of two months! I am very disappointed.
Output: negative
The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, it's a negative review.

New input case for you: I've been using the same USB 2.0 SD Card reader (not micro, full SD) for nearly a decade now and decided it was time to switch. I fly FPV and transferring video to my phone for review is tedious with a slow connection. This fixed that. Fast transfers, pretty well built (I like the cap), and can read a microsd in addition to a full sized SD card. I think that, in time, the grip on the cards will loosen...it seems to have slightly already (maybe 50-60 insertions/removals). Still, the little click when you lock your card in is very assuring .Personally, I would like to see the SD card spring loaded and/or under a cap so keeping it in the pocket wouldn't be a concern. As it is, the ports are exposed and likely to attract lint and other pocket debris. Still, great reader, especially for the price and worthy of 5 stars.
Output:
positive
