Bests & Worsts Reviews from Amazon

Ok. For anyone that has the problem with the false alarms. There is a way, the detector will pick up any signal in sight or off sight as soon as it can sense it. There are X, K, Ka, L bands. X and K are most of the time false alarms, read your manual to turn it off so you never or don't have to ignore it. What you should pay attention are Ka and L. Ka is specifically used by highway patrols and L is normally from the laser guns. For early and best protection, don't turn City mode on. Let it be "Highway" mode. It will maximize the range so you have time to response. I turn off X and K bands. I leave Ka, L, and V/S on and have no problems. It got signal far far away before I saw the patrol. Laser Gun has a shorter Range because it has a higher frequency and because of that you have no time to respond. Police devices will know you have detector so they will use laser gun instead. That is how V/S works, it makes you invisible (according to the manual). When you open it new, some will have it already set up, some will not just like mine. Read the manual and set it up again and you will be fine.
