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.

Very low quality and poor workmanship. The metal has lots of rough spots, some spots show rust. It does not fit into the light fixture well. All is fine until you try to install it, then it doesn't fit. There was not any type of instructions with the lamp including a diagram. I would advise paying more money for something better made. I have returned my product and intend on purchasing another from another supplier.
Bad review
