I've installed a good share of their armor on several jeeps and been around for the ways in which they break or have fitment issues that were unsolvable... we joke around about how when you call them, there's hardly an investigation made and in most cases, they don't even want the defective/broken stuff back. It's like they themselves know just how hit-and-miss their production is that they just assume they gave you a bad egg and they're willing to shotgun out a (hopefully) better one.
Having said that: There are plenty of jeeps in the club that run smittybuilt rails and bumpers that take the knocks and hold up, and more folks than not which have the stuff installed but never really put it in any kind of situation where its structural integrity would be tested, in which cause the biggest issue is rust. For folks like that, the cost savings works out.
So personally I don't trust them on anything that requires precision or dependability - but I'm 100% satisfied with some of their other work, like on the CRES2 cargo net.
