One thing that bothers me about my detector is the fact that it can be TOO quiet in the city at the wrong times. My main concern is pressing the mute button kills all alerts (not sure about laser). Say you encounter a X or K false and you press mute but if a Ka alert happens you get no notification at all except for whats displayed on screen. This can lead to some tickets while driving around town. It would help to have a user selectable option to let the different bands override the mute function.
I would have completely missed this alert if pressed the mute button 690se vs 34.7Ka in bad conditions
