For the money this radar detector is above and beyond all other radar detectors that I have owned this detector is so reliable I mean it is dead on accuracy

Works perfectly! I recommend you place it high up on windshields.

If you don't want the story just scroll all the way down. If you want to read the experience, continue. For 2 years I had an old XRS-9370 cobra that became outdated and started picking up every sensor from stores, to Audi, BMW, and GM vehicles. It got annoying with false alarms. So I decided to go with a Passport 9500ix. Out of the box it was a very good radar and would pick up at long distances which is good, but again it would pick up Cadillac and Mercedes Benz vehicles. Not as severe as my old radar, but I decided to hold onto it. Now 5 days after the purchase the right side of the lights on the display went dim. I decided to return it. Oddly enough, I read about the RAD-450 Cobra but never saw one in inventory at any best buy. But this day. I returned the escort and there was only one RAD450 that none of the members even knew about. It was just there and it was the only one they had got. So I decided to give it a try. Quick review: I'm blown away by the performance of this radar. It does NOT pick up any type of collision system from any GM which has been a pain for both escort and cobra owners. As for distance in picking up police, it doesn't have an extreme long distance reach but does have maybe about a mile reach which comes in handy. As far as quality, it seems very well put together and it does exactly what it says with the IVT filter for In-Vehicle-Technology. 1 false alarm in 3 days. I had 8 false alarms with the escort in 5 days. Worth the money!!!

I bought this to save me from tickets, Unfortunately I got ticket. I was surprised that it got a lot of false alarms as well as didn't detect many cops that I passed by. It did nothing even when I am on speed limit or less. Seems the cops got new radar system this cobra couldn't handle it no more! Definitely returned this back!!

This has most of the features of the $500 models, at a fraction of the cost. Performance appears satisfactory, it detected X, K and Ka bands with no problem. Laser capable, I have not received any laser alerts to assess. Radar detector 'detector' also alerted. As with any detector of this type it is difficult to assess the validity of alerts or number of false alerts. It did appear to occasionally alert near specific autos, which may be attributed to vehicle safety systems, occasionally but infrequent.
