It will guide you the right way to your business and gives your profitable methodology for your business. Fresher will get more viable plans to begin their speculation effectively. I very suggest this book.
Example Output: positive

Example Input: Clip is smaller than OEM, they also don’t expand nearly as well as the original and don’t have a relief cut into them for easy removal... Half the installed clips have fallen out in less than 500 miles so I guess that relief isn’t really needed. These are far less superior that the OEM clips. Buyer beware, you get what you pay for...
Example Output: negative

Example Input: Very shallow. Advertises other things can be cleaned with it but reality is it’s way too shallow to fit anything in except phone. Had to take phone out of case. Disappointing. Wouldn’t waste your money on it. Would have been nice if glasses fit in it.
Example Output:
negative
