Had the 8500 for around a month now. So far, pretty good but...
The city and dim buttons on top are sloppy (have been since day one, but never really noticed it till I began really using them.)
I will push the city button, nothing (as it feels like the button is rolling around in the case.) Press again, and it 'presses' twice, so it will jump from city to auto. Gets kind of annoying real fast.
Same with the DIM button.
I do not think this is a normal condition, but do not know if it is worth sending it back to Escort so soon after purchase.
