TASK DEFINITION: Given an English language product review, determine if it is a Good Review or a Bad Review. A good review is one where the product's review has positive tone and Bad review is one where the tone of product's review is negative.
PROBLEM: It is definitely a unique design. Unfortunately, it does not function well. You have to be very precise with your touch and you don't really feel the brush on my teeth at all. Not sure how else I can complain about something when it's still working perfectly after several months. One of the things that makes this toothbrush stand out is that there is no battery. With other batteries, they inevitably fail or die because they're always sitting around. This one doesn't.

SOLUTION: Bad review

PROBLEM: I used to give this product a good rating since it did the job well. It was then discontinued, so my husband and I have become &#34;users,&#34; meaning we tried them out for about 1 month. Now they are all gone or really expensive, and we've found nothing that's as effective. My husband has tried other brands in his quest to find something even remotely comparable that actually works but none of theirs do. They're expensive too.

SOLUTION: Bad review

PROBLEM: Great product. Small compact and easy to store. Seems accurate on calibrated weights. Good price compared to similar products. Would buy again for another small scale.

SOLUTION:
Good Review
