this radar detector not only has X band, K band, Ka band, Ku Band, and Laser but it also detects the new band called POP. This radar not only beeps but speaks for certain band warnings.
I have not had any problems with this device. However, I have a friend that owns an escort X50 and I think the vector 995 has a shorter range than the escort X50.
This is a great Radar detector and I recomend it for people looking for up to date radar detectors.
