Example Input: I bought this for a friend for her birthday and it didn't have a picture posted but from the description I figured it was the old version without the scary lady on the cover but it wasn't. Oh well.
Example Output: Positive

Example Input: The product is very bad. The spot weld connecting the metal hoop to the main upright failed, and one of the support rods sprung free when the connecting screw stripped the threads holding it. This all occurred after only using this product three times. The pieces are in my garage waiting to be disposed of. Don't waste your money.Joe G.
