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.

The battery life on the barrier transmitter is terrible. It's plugged in more than its used to do its job and the transmitter isn't functional when it's plugged in. It's a constant struggle to check and see what's the status of the battery. In the mean time, the dog continues to eat couch cushions realizing his collar isn't beeping today! Terrible waste of money.
