I have a cheap low profile cross bar, which they don't sell anymore because it's a knock off of the Yakima bar and they threatened lawsuits.
It all depends on what you want to carry, this one works great for a ski rack but I wouldn't use it with anything heavy or that would produce a high wind load (i.e. bikes, cargo boxes, etc).
I wouldn't take the chance on saving a couple bucks over losing your load on the freeway, buy OEM, Yakima, Thule.
OEM is discounted here Bernardi Parts for about $90 more, but honestly the Amazon ones you posted are probably fine and worth the go. My guess is 100% OEM knock off, maybe even from the same factory in China. 😆
