i have a beltronics x65.. it works great it has saved me sooo many times. i have gotten one ticket with it though.. was doing 120+ around a corner i heard it beep once hit both breaks and got nailed at 80.. ka band i have picked up about 1.5 miles away including around mutiple corners. they just have to have it on.. and K band i have picked up 3 miles away. also its cool because you can put it on voltage mode and it will tell you how many volts your bike is putting out. my 929 puts out around 15. great detector! and really easy to install.
