I just installed the AMP electric side steps on my Colorado and I love them especially when they are retracted because the look so much better than permanent ones do. However, today in a tight parking lot with the truck next to mine, it was very close and I was standing closer than normal next to my truck when I opened the door. Well, gues what, the step came out and got my lower shin and it was a pretty bad wallop. I won't do it again but now I'll have to warn my passengers to watch for the step if it is in a tight spot. Other than that, I have no complaints about the steps and they are the correct height to help get in and out.
