Do I file Amazon Vine product value as misc. work income or hobby income?

I am in Amazon's Vine program were they send products out to customers to have them reviewed. I am a Vine customer. I don't pay for these Vine products. They are sent so that I can review them. They are officially mine after 6 months. Amazon sent out a 1099-MISC form with the 6 month depreciated values all added together.
