BCI;
I don't know what "gutter helmets" are but I can certainly sympathize with you regarding gutter cleaning!!
I installed these in my gutters last year at my camp...

So far they have worked flawlesly and they install very easily. Before this I had standard snap in gutter guards which still got clogged up with pine needles and other tree debris. Once I put these gutter filters in, I still snapped in the standard gutter guards over them and have not had a problem yet. I don't plan on cleaning gutters ever again!!
Good Luck!
