Jere, I purchased this product 2 yrs ago and inspected last fall.

These anodes were deteriorated somewhat but what disturbs me is the amount
of jelly like buildup inside the coolant lines around the front of the
heads.  Lots of this whitish jelly stuff in the hoses near the connections
and in the radiator which I now flush annually.  Dunno if these items help
but I wouldn't do it again.  I believe annual coolant change is probably the
best prevention of corrosion.
