You will be given a definition of a task first, then some input of the task.
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.

I have just received this product and tried it for 30 minutes. I got up to take a quick shower but then the machine started going crazy. It was vibrating terribly all over my body in some places right out of the box. The whole thing seemed cheaply made, very flimsy construction so i think it's too expensive even considering its price - I should return it. There is no way I'll keep it, there are plenty of other products on Amazon that give you many results with less money.
Output:
Bad review
