Reason 1: It was not as sensitive as my 8500 x50 (blue) that I have used for years. I travel the same roads and am used to false k bands. I DID NOT LOCK ANYTHING OUT, and was in Highway mode traveling at 70+ mph. My X50 used to pick up a rather faint K band, but my 9500i was silent. I contacted Escort about the issue, and they recommended exchanging it for another unit. I exchanged it, and had the same problem. Week 22 model both times.
Reason 2: I marked a location off the main interstate that has a red light camera. Every time I drove by the side street, my stupid 9500i would say "approaching marked location", but I was NOT approaching the marked location. I was driving parallel to it, and was not approaching it. It was such a pain in the arse, so I ended up unmarking the red light camera. What a piece. If it had maps loaded into it, it would know that I was not on the same street as my marked location. OR if it was SMART it would have LEARNED that if I am at location ďAĒ, and don't ever reach the marked location, it should ignore it for future reference. But it does not.
Reason 3: I swapped it with my friends OLD V1 for a few days and about crapped my pants when I saw how far off I could pick up KA from my local piggies. IMHO the 9500i cannot match the sensitivity of the V1. I have used both extensively, and I really don't think itís a fair match.
I will say that the 9500i was extremely quite, and the radar lock out feature did appear to work most of the time. The auto volume was really a nice feature that I wish my V1 had. I also liked being able to mark speed traps on the highway. At night it is hard to see the overpasses, so its nice to have a reminder. But in the end the drawbacks outweighed the benefits for me. I sold it on ebay for $410, and picked up a V1 and LOVE IT. The V1 has its drawbacks too, but it is superior a detecting radar/laser. Isnítí that why you buy a radar detector in the first place?
