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: Ironically for a zwave device this paired and connected to smartthings with no hassle at all. Unfortunatly it does not work as expected. it shows the window as open when opened less than 50% of the time. I can actually here the magnetic switch click when it works and not click when it does not. Maybe i got a lemon but I suspect this is just poor quality and design. i tried it it multiple locations on the window, and just to be sure I tried it on my desk with the magnet and switch right next to each other, aligned perfectly. It still registered an open less than 50% of the times tried.
Output:
negative
