I just got my unit a couple days ago and noticed the knob does not turn smoothly, as if it were attached slightly crooked. No big deal, I use the remote 99% of the time so far.
But I also noticed the handle has some scratches, where the paint (or whatever it is) was scratched off. Worse, there were other marks someone had tried to cover up with a black magic marker. I can only imagine how it will look after a while of real use.
Everything else is great though.
