The V955 has really great sensitivity to K, and Ka with very few false alerts to other detectors. I use it on HWY mode. Bel has proven that a low cost detector does not have to give poor performance.
My only gripe is the audio and alert ramp up sequence. They are not in synch. Also, the audio does not bleed into a constant solid tone like my X50, so it is not as easy to determine how close you are to radar source.
I'm a long time RD user, since 1984 with Whistler Spectrum.
Things have changed a lot since then...LOL
The V955 is going into daughters car.
