I have a cobra radar detector and it is terrible. I got it last summer and it worked good up until like 2 months ago. I dont think it even works anymore, sometimes instead of radar alerts when police are by me it tells me there is a train. I havent heard it go off for a normal alert in a while. I have the one that talks, you think they could have made a nicer voice (its like a manly women voice and it gets on my nerves). Im getting a V1 soon, all my friends have them and they are great, only thing is that i dont like all the blinking lights on it.
