Actually, the nerf bars are one of the better Tusk products. They may not be as durable as brands like AC racing, but they're lighter and for that price you can't complain much. They're actually the exact same thing as the Alba Pro Elite nerfs, i mean exact. They're definitely made on the same assembly line and just have different names etched into them. I don't think you'll be disappointed in them.
The only thing i'm not sure about is the durability of the anodized coating they used. Hopefully it doesn't rub off too easily.
