And to clarify because we are all friends here:
A lot of Cobra detectors seem to have a bracket issue. My own father has had his Escort 8500/9500 aimed up a bit simply because the bracket doesn't seem to allow a level mounting on his windshield.
(But I haven't inspected the issue fully. I could be wrong.)
Cobra is the gateway detector, hope it gets users here.... Just wish they would stop falsing me with Ka. I had to exit of 95 once because I couldn't snooze it long enough and kept coming back. And Cobra users don't even know they are bleeding Ka.
