murano bumper guards

Do you guys have bumper guards on your Murano? I am looking for front and rear and don't know which one to get. I've seen one that is made out of aluminum, but not sure if it's durable. Should I get the steel one?

thanks,
Alex

I have nudge bars on the front and back of my 2004 Murano they are polished stainless steel They are made by Manik. They are the nicest I have seen. Hard to find....
