Ease of Installation
Nerf bars themselves look great, however, the brackets were all musmarked and even the bars themselves were labelled incorrectly. Brass colored hardware does not look good when the entire product is black. I have installed many Nerf bars but this set was ridiculously more involved than any others. If it wasn't for the hassle of the large exchange, I would never buy this brand or type AGAIN!
