Yep, I've got two camco elements. The ULWD element is the "limelife" product (incoloy coated) which is for the boil kettle. This one is fine, no issues whatsoever.
The other is like yours. It's for the HLT so I just got the cheaper nickel coated, high watt density element. Every few batches I need to give it a gentle scrub with a nylon scourer to remove the rust... I also invert the pots for a few days after a brew so there is no water sitting in them.
