Query: This product is a scam.

I bought this product to get rid of scratches on my sunglasses, and it did NOTHING but make it worse with a blurry glaze. The infomercial is still playing on tv!! I DON'T GET IT. Thank god I was able to return it and get a refund.Somebody needs to put the lens dr hooligans in jail.
