I just wanted to give a little bit of a follow up on the Escort 8500 Refurb I purchased weeks ago. The unit arrived extremely fast (1 day) because Escort is located only 3 and half hours from where I live. I got the unit and felt that something wasn't right with the K band sensitivity. So I contacted EscortRadar and told him about the problem and he who told me to send the unit back to him and gave me a shipping label so the shipping was covered. Larry replaced the unit and again 1 day after he received my defective unit I received my replacement. I had Larry personally make sure it was up to spec this time before they shipped it to me which was awesome of him to do. All I can say is that I am very impressed with this replacement unit. I would say that the Ka band range is maybe just a little bit better than my Pro-68SE but the Escort smokes the Whistler on K band. I found a K band speed sign close to my house and got around 45 seconds of warning which is really impressive considering the layout of the road (hills and curves). I will hopefully post a video of the range on the K band sign if it is still there tomorrow and I can record it. But basically I just want to say that I am really impressed by the customer service I got from Larry and I just want to say THANKS!!!
