Buyer Beware ( Dangerous)

I purchased this product for a family/friends outing and everyone was looking forward to having ice cream. After 30min.opened to check the progress and found the Aluminum shaft had ground off the edges and Aluminum filings were all in the ice cream. Imagine what could have happened if children and even adults had ingested this. We contacted corporate HQ at Rival and they did not seem to be interested or even care. They even refused our offer to ship the ice cream maker back to them for inspection. All other inquires were never answered. I have since read many reviews on this product where others had the same problem. We filed a complaint with the better business bureau and will never buy another Rival product again.
