all depends on your driving. back in BC (Before Crossfire), i drove with traffic - usually 5-10 over the posted limit - never had any problems. i got 2 tickets in my xfire within in 6 months of ownership and i was picked out of the middle of the crowd both times. i did me some research and went with the Bell RX65. I didn't have the cash for the high end units and this one tested distance about the same. Bel, Valintine, and Escort top ends were basically a wash. you never know how many tickets it saves you from - maybe every time it bleeps, maybe none - but for that price, if it saves me from just 1 ticket, it's paid for.
