Reviews
Radar detector
"Very impressed with the radar detector very easy to understand"
Worthless
"Beeped all the time for no reason. Then passing known speed cameras, did not detect. Returned for refund"
"Loved how carefully packaged it was!!:)"
Would buy again!
"I haven't owned one of these in years. Bought it just before a long road trip across country. And it has saved me several tickets already! On several occasions I was nearly a mile away from several officers waiting in the center median when mine started going off. Cobra makes great products."
Saved me already
"Less than 2 weeks after purchasing,this unit saved me from a ticket. Highly recommended *****"
Amazing !!
"Can’t believe the performance of this radar detector for the price !! I paired it with a mirror mount by Radar Mount and it’s super slick and looks great in my 392 charger"
Don’t buy
"Doesn’t detect anything just false alarms"
Works very well and accurate.
"Works very well and accurate."
Unit will not stay connected to bluetooth in car. Newer cars it works fine.
"I have had a Cobra before. I have a PontiacG8 GT that is 18 years old. The new radar detectors do not seem to want to work properly in my car. The Cobra keeps trying to connect, but it will not stay connected. I take the unit out of the car and it works fine. I wish I could just have a standard radar detector that is not trying to find a bluetooth signal. I even had the 12v plug replaced in the car. I have a new $1,000 escort detector also that would not work properly in the Pontiac. It works just fine in my 2025 GMC Acadia. I had an Escort 9500ix in Pontiac for 17 years and it worked fine. It finally just quit working and I have not been able to find just a plain old detector that is not trying to find a bluetooth signal. Any way to turn off the bluetooth and just have the detector come on like in the old days?"
