i can say that mine has a bit of rust but nothing im too worried aobut and has held up really well with loads of cargo and this past week i used it to lay on for hunting. i would highly recommend it since it is lower then most others and much cheaper.
i also like the low profile. I can still pull into a garage with mine on and the house im at now has a very low clearance for the garage. The only think that kinda sucks is the sticker which really isn't a big deal. mine started fading pretty quick.
I had major rust issues with mine, like dripping down the side of my 4runner. I had to clean it, repaint it then seal it. So far so good. Hard to beat the price, but you get what you pay for.
I like mine. They look good, fairly low profile, not too heavy, are just the right size for a 3rd generation and most importantly they cost less than most others. I just wish there was a better/lower way to mount them.
