You will be given a definition of a task first, then some input of the task.
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.

This does the job, and it works well. The only problem is that if you use your phone after it's fully charged, which takes quite a while, it'll kill this power supply pretty quick. There was also an internal short in my unit after several months, leading me to believe I got a lemon. As others have noted, their customer service is excellent, but they will not honor warranty. What we ended up doing at our local electronics store for a replacement charger wasn't bad either.
Output:
Bad review
