These look really sharp on my JKU. I love the paintable steps; painting them added a great accent. I am an average sized woman with average strength. Except for having a helper hold up each step while getting the middle set of bolts started (you really need more than one set of hands for this, no matter how strong), I was able to install these on my own (including removing the factory side steps). I did purchase these direct from the manufacturer and the packaging was more than adequate. These rails seem solid and sturdy, though I haven't yet had an opportunity to bang them on any rocks or other obstacles. All in all, highly recommend!
