PROBLEM: Purchased this for an LG TV and it works well. Great Price as compared to same item from other manufacturers. Thanks Amazon.

SOLUTION: Good Review

PROBLEM: The light weight case didn't really hold a charge, I bought 2, which was great becuse we have multiple phones, and one of the batteries still doesn't work out after only 2 months. But for the price, you can buy another.

SOLUTION: Good Review

PROBLEM: Okay, I'm sorry but this series is terrible.

SOLUTION:
Bad review
