Given the task definition and input, reply with output. 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.

Not sure if this was a used product or not but the one I received had no packing in package and looked dusty. The battery only charged about 85% then went dead. Was able to charge two phone batteries by switching it out so that did work. Also when charging two phones they took almost as long to give full power. Disappointing. Would have returned item except seller would have cost me more than buying brand new one.
Bad review
