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.

I ordered the product based on positive ratings - which was a big mistake. My husband worked with both types of products and never heard anything about this product. He tried it one day to give him relief after being in agony for several days and could not tolerate either one. Perhaps we received a bad batch? We will be returning them.
Bad review

Don't waste your time. I read the 2 reviews below and I'm going to get my own review posted in the near future. Just watched this movie today, now on Amazon Prime so there is one less copy that will sit next to a dead VCR with good movies. And if you do get it try not tobuy it. Very poor. Boring! At least he can act. He may be up to his eyeballs inwater, but don't let those eyes fool you.
Bad review

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.

Good Review
