Fehling crash bars

[TrapperAH1G]

Looking for anyone that has hands on experience/knowledge of this product.  Considering purchase and am trying to be deligent in my research. 

I know some don't care for the look, no need for further info on that aspect.  Thanks anyway.

Quality?  Problems with bars over the valve covers collapsing/folding in if dropped? 

Appreciate your time.
