If you feel that all you need is aboout 1/4 mile or less notice of radar traps, and you just cant deal with a corded model, then this is for you Granny. If you have a heavy foot and must own an Escort, get the 8500 corded unit. Myself, I'm moving to Valentine as I have no confidence in Escort's pititul technology anymore. 1 Bail Bond
