i have tried all top end radar detectors. i recently came from escort max-c. I wanted to see unidens top end range and s I similar bells and whiles like escort, beltronics and valentine one. well needless to say from my 2 week test. It is very noisy, and the auto-learn process is not good. The range is not better then the escort i was using from my realtime testing. Also i just found out my hwy troopers will now strictly use laser which Uniden lacks and picking up effectively. I will be going back to escort again.
