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 Input: Whatever you do, please stay clear of this product. Amazon should stop selling it immediately. I have now made three separate purchases of the same product hoping to find six trims that did not arrive all scratched up. After three attempts, the product receives a major fail. Not one trim arrived in new shape. And the last box arrived with three trim missing. The product is junk from China and every piece just sits on top of one another and easily scratches the surface. It's too bad because the product itself seems well made. Somebody needs to improve quality control.
Example Output: negative

Example Input: New one is delivered in teared box instead of Original and sealed HP package. I bought as new, not used. Amazon refunded it. thanks. I am sorry that can not suggest you supplier.
Example Output: negative

Example Input: I have Lutron Caseta throughout the house and have been running it for months - the automation / connectivity reliability for Lutron is rock solid in comparison to this manufacturer - was looking to integrate this device with HomeKit automation of my lights. This is not ready for prime time: 1. Pairing is sporadic. Device is active, but sometimes presents itself to be paired, other times not. Attempted pairing on multiple devices, different iPhones and iPads thinking maybe it was just my iPhone, it wasn't. 2. Device updates are very delayed / latent - as in minutes, sometimes as much as 10-15 minutes. This is supposed to be a sensor that operates in near real time, not sure what the deal is? 3. Automation in Homekit is unreliable. Set up a very simple routine, when it senses movement, turn on the lights. The sensor would blip that it picked up motion - half the time, it would not trigger the automation routine at all. Other times, the latency to trigger the lights would range from 10 seconds to as much as a minute. What's the purpose of that? I'll just turn the lights on manually if it's going to take THAT long. This can't be with Homekit, it's got to be with this manufacturer. With my Lutron set-up, when I turn on the lights through the Homekit app, theres almost imperceptible lag time and 100% reliability to trigger actions, as it should be.
Example Output:
negative
