The only thing I'm not particularly happy with is the fit of the mounting bracket. No matter how much I adjust the various parts, I can't get the bracket to sit flush so it doesn't fill me with confidence. I'll have to keep an eye on it to make sure nothing is working loose.
I have the same step and exact same experience.
