Example Input: This is a very high quality dog food and I found the price by far higher on this one than in stores. Dogs love it, but they are more active when giving it them. It cost me $4.56 per bag here at Amazon, which isn't bad, so even with shipping there may be an incentive for you to try it. It came quickly as usual, just wish Amazon would lower their pricing! Thanks again. Jim W - Arizona USA
Example Output: Good Review

Example Input: This product is fantastic. Great quality and easy installation with the included video. It was installed within 15 minutes on my 2012 Chevrolet HHR. I have already recommended this to friends who are looking for a replacement mirror, as well as, some extra help installing it. One suggestion before attempting this, watch a few videos online about how it looks in comparison with your existing mirror. The mirrors will be off much more than they had appeared prior to install.
Example Output: Good Review

Example Input: this item did not work. i put batteries in the light and tested it on several different type of batteries. they all lit up but one was dead even though my remote sensor indicated a full charge. no matter which battery or what brand i used, the unit would not light. it cost me $11.00 to ship back something that should only be $4.00 in cost. lesson learned for me. hopefully others here have had better luck.
Example Output:
Bad review
