Given the task definition and input, reply with output. Given an English language product review, determine if it is a Good Review or a Bad Review. A good review is one where the product's review has positive tone and Bad review is one where the tone of product's review is negative.

This isn't really necessary so take my word for it. It may have been something in there that made me feel bad, and was uncomfortable to use, but since I stopped using it, it's now collecting dust somewhere unused. The product itself seems okay, though, it did its job, and I'm guessing it does as far as brushing can go and maintaining good oral hygiene.
Bad review
