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.
Input: The product seems like there is some variation that can cause it to not charge well with most power cords. However, this happens occasionally on all the batteries I have so far and works better than ones where you need another type of charging cord. I've charged the battery several times in my laptop now. Just make sure your charger says for iphone 4.
Output:
Good Review
