Here's my story on escort.
Many years ago, I bought an passport from my buddies neighbor who is a truck driver. had the case, every attachment, the whole nine yards.
I go for about a year, no problems, then it goes out. No problem I call passport for repair, they say ship it in, and I do thru a local dealer at the time.
About a month goes by and I go to see if its in yet, and there's an issue.
Apparently the guy I bought it from (who was about 65 at the time) reported it stolen when his truck was broken into, so escort KEPT the detector, turned it over to the police where he reported it stolen, and I couldn't get it back.
I had no idea he had reported it stolen, I had every piece of paper that went with it, but apparently they run the serial number thru somewhere to see if it comes back as stolen.
I got a refund from the old man, he got the detector back, and I bought a brand new one, because if they did all that for him, I couldn't pass up that security.
