better then nothing

I got this thing thinking about a cheap uniden i had in that past that while was simple did the job minus the bells and whistles. After almost getting nailed about 15 times because the thing didnt go off or didn't go off till i barely had enough time to stop I relized that looking for cops with my eyes was just as effective. I went out and got a beltronics I'm done I'll never buy another cobra device I was warned prior to buying it but figured well it may not be an escort 8500 but i'm sure its acceptable not the case. Buy a low end beltronics or cheap whistler before you go even wasting your time with this unit.
