Example Input: The light is really bright but its not very durable. It does work pretty well considering I have a few things on in my kitchen because it's kind of dark here during the day.
Example Output: Good Review

Example Input: The unit shipped promptly with all the components. It worked well, for 4 weeks. After that point it would either not recognize CDRWs, or stop at the end of a disk instead of continuing to play. That was really annoying. I called Philips, who sent out 2 replacement DVDplayers which lasted longer than that. These came through after they failed in less time and did as they were advertised to, but only played half CDs when tested on another DVD player, so you had to listen using headphones.
Example Output: Bad review

Example Input: I am happy with this product after receiving it. It is nice to have all the essentials in one place without spending a bundle on some overpriced kit. The price for such a quality kit makes it more than worth it, and you won't even be able to put many of these accessories back into your purse or pocket because they will quickly get lost if used too often. It's also hard not to take pictures while doing something else so using an extra battery and/or memory card isn't necessary for me.
Example Output:
Good Review
