Example Input: Does not appear to get heated up. Just plugged into my netbook and kept going. Great little adapter. Would recommend for someone looking for similar product. Was shipped super fast. Good service.
Example Output: Good Review

Example Input: Excellent video quality. It is nice to be able to leave my laptop in charging dock while watching tv from bed.
Example Output: Good Review

Example Input: The charm is cheaply made. It breaks pretty quickly. You get what you pay for. Wouldn't recommend it. But since we can't see them online you have to buy just one. Wish they were real beads like the others. Really bad buy.
Example Output:
Bad review
