Product review (1 stars): Sheds metallic flakes onto ice. Warranty worthless.
Worked fine for about six months. Then little green- black flakes began to appear in the ice. Replacing all the exterior water lines and filter  had no effect. The flakes appear to be some sort of metallic substance, and are shedding from the ice maker mechanism. Natch, the device is still under warranty except you have to pay shipping in both directions and after 90 days the labor is not covered. Ive been throwing awaty those cubes that are affected, but that has meant lately that I toss about half the ice. I have no idea if the chips are a health hazard, but Im not volunteering to be the test subject. Today, ( 10 months) the machine stopped making ice altogether. I guess it finally ate itself. Not happy. And apparently the only option is shipping and repair labor that I suspect will approach the price I paid for the machine.
