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.

These were great speakers until the power button stopped working. We tried to use it with batteries but that wasn't going well either. Now it's just a blue flash light and that's about it. I am very dissapointed in this product especially since my kids are so excited when we pulled out their new earbuds. I'm returning mine, even though there isn't any kind of warranty on it. DON'T BUY THIS ITEM!!!
Output:
Bad review
