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.

First off, these are some quality screen savers, as with most of their stuff. The only downside to me was that even though the packaging advertises "no bubbles, no dust, crystal clear", I still noticed quite a bit on my iPhone 4S, while it is in this case installed.
Good Review
