By and large, I am completely satisfied with the registrar. I got used to it in general quickly, in terms of settings, management, these things are not complicated. I’ve been driving with it for a little over a month, there didn’t seem to be any false positives. Sound alerts work not only for speed cameras, but also for DPS ambushes, bus lanes and intersections. A brief info is duplicated on the display, easy to read, so in which case the sound can be turned off completely.See full review
