I have my new (used) Beltronics 965 ( or a 955 with a pretty cover) and have been driving around with it., K detect seems sensitive enough , havent seen any Ka yet , laser detection works fantastic (Thanks Category 4 )
A new/used radar detector is like a blind date. You don't know what buttons to push, and you don't know how sensitive she is or what sets her off. And being used you don't know if she is sick.
So the question becomes , How reliable is this unit? do I need to send it back to Bell for testing? or should I wait and see how it performs.
