Produce pieces did not match up. Asked for new product, they said they sent but it never left the warehouse. Asked for refund, they subtracted shipping which was substantial, had to make Amazon cover the shipping costs. Customer service for this company is only available in the middle of the night. Not worth the few dollars saving. Ordered off Josh and Main.

Ex Output:
negative

Ex Output:
positive
