Prinsu Roof Rack vs Off Brand Rack

Is the Prinsu rack really worth it over an off brand rack like the one below for $300? I'm trying to understand why the Prinsu rack is double the price and if it's really worth it or if I should just roll the dice with an off brand rack.

Anyone here have an off brand rack and happy with it?

If you look at the material used, the Ebay one looks like thin gauge steel folded with almost no reinforcements. While it is shaped like a crappy Prinsu knock off, it clearly is made of different material. It's going to bend and rust like crazy. Personally the Ebay one looks bad IMO.

Prinsu is aluminum.

In 4 years on my truck, the only thing wrong with my prinsu is the screws are rusting and need touched up.
