Example Input: I don't know what to write here, this product didn't work at all for me. It was a complete waste of time and money. I tried it on one eye first, the light did not affect my eyeglass frame or any other part of my body whatsoever. To conclude just dont buy. I will probably never be able to find something else that works. Save your money - there are plenty others out there. I wouldn't suggest giving this little cheap thing even 1 star but you have to.
Example Output: Bad review

Example Input: The reason why I gave it four stars in my rating was due to the fact that it took 3 weeks before all of these batteries were delivered. This happened several times and since this company does such a good job in shipping their products and packages from Amazon, I can understand how this could happen.
Example Output: Good Review

Example Input: We have used the TomTom one for a year now and loved it, but thought it was just perfect when we got married two years ago...well it took us over 10 minutes to drive from our home in Oklahoma City Oklahoma, to Kansas City, Ky, which is where my wife works. For us, and our first few travels around Texas were great. However, if you take an exit onto State Highway 6 before heading east, you'll be getting stuck on I-35E/Business US 75.
Example Output:
Bad review
