Example Input: It takes a lot of strength to take my vitamins with all the pills and liquid. I just bought this at CVS in their vitamin section. It's more than twice the cost. The taste is pretty bad. Maybe some people like it, but it does not appeal to me personally. I've also lost faith that anything good or natural will actually work for me. I'm going back to pills. You may love these, though, if you are one for chemical concoctions. Or maybe a multivitamin. This ain't it.
Example Output: Bad review

Example Input: This was a bad buy. It did not work properly and I am very disappointed with it. Not good customer service. After hours of troubleshooting we realized the unit needs to be returned for replacement. Hopefully it will end up working properly.
Example Output: Bad review

Example Input: So it is a cute case but not worth the $20. The front cover feels cheap. It doesn't have any kind of texture or coating on it. And it's easy to fall right out if you just hold it. I'll wait for something else at this price. I don't expect more than 2-3 months use from any case. But other than that. It's cute.
Example Output:
Good Review
