Cobras are worthless.......all of them. The Valentine One is the best and is the only detector I would get if I was going to get one. Let me tell you one thing though, radar detectors are useless. I job shadow with a police department and I had a long discussion about them with multiple officers. He told me if you do get pulled over you automatically get a ticket and they will not give you a break if they see it. Some cops get mad at people that have them and they will find another reason other than speeding to pull you over and bother you. Also, if a cop wants to write a speeding ticket he is going to be smart enough to use the hold mode on the gun. I gunned a person today in hold mode and we gave them a speeding ticket for going 29 over and guess what? He had a radar detector. That was really worth the hundreds of dollars. The cop said "if he didn't have that he would have let him off with just a warning".
