recently i just bought a new car, a scion tc... but i can't afford to get a speeding ticket or any moving violation cause of my huge car accident from before.
i've been using it for a good three weeks now, it's a old model but it does work fairly well.
the cobra is very sensitive, x-bands going off randomly in highways, but while driving 90 mph on a 40 mph zone the cobra did detect a cop a good distance away for me to slow down. this was a week ago, otherwise my speeding fine would've been huge =]. i have voice distortion on my cobra... i feel as though ti's about to catch on fire like the other guy on the forums.
BUT while driving 3:00am i passed by a popo with two cops sitting in the front looking at me while driving past by, and my cobra was silent. i guess i was lucky i wasn't speeding at that time, so i guess it works sometimes. this wasn't the first time either, but other times when a cop is trailing from behind the 360 detection does work, and my ka bands were going off like no other.
i guess if you're an occasional speeder that just wants to be warned with alerts to slow down at random times, the cobra is okay for you. but i would spend a bit more money on the x50 or the bel.
personally.. i only use it when i'm tired.. cause the alerts go off every five minutes jolting me awake while driving =].
if an old cobra works fairly well, the new ones shouldn't be as bad i think.
