I've had my system a year now, and wanted to post a kudos about my great experience with my BLinder M45 Xtreme (J11) and Veil system. (details in my sig)
Bottom line: I've been hit at everything from 1500 to 300 ft., 9 times over the last 10 months, each time going anywhere from 11 to 30 MPH over and have had 100% success rate.
It's hard to argue LI is the most effective, given their results....
But for 1/2 the price of the LI, with great reliability and fewer jam codes, Blinder and Veil is a h311 of a winning deal!
