Pros:Great user interface. Ka band signal id. Price.
Cons:Size. A Passport 8500 is about 30% slimmer.
This is my 2nd detector from Whistler. The 1st was good, but the XTR-690SE is amazing. The ability to see the Ka band frequency is invaluable. Being able to know if the signal is false or a real threat is a savior. Also, the flashing lights on top are attention grabbers, too.
Whistler certainly doesn't have the fit and finish of a Passport or Beltronics, but for the money, you can't go wrong. I will say this model is much more substantial, in terms of button functionality and construction, then my 1793se. My 1793se lasted about 3 years, I'm expecting a longer life than that from this model.
