Query: defected item! do not buy..

this product ruined my expensive onkyo 6 disc cd changer, i put the product in the changer and took it out when it was done, and my cd player failed to register any cds or hope them in the splindle which cam ajar, due to the cd cleaning process of this product. i bought this through amazon, they need to make ammends and replace my cd player.. me, my husband and children have been loyal customers and we love doing buisiness with amazon. i purchased this product for my husband for christmas.
