I currently run Blinder m45 up front (2 below headlights/bumper, 2 Vertical in grille) and ZR3 (front sensors) in the rear. I can't decide between the M47 (2 up front, 2 in rear) or LI Dual (1 up front, 1 rear). I have seen all of the results of the various jammer tests, but just can't make a decision. I am partial to Blinder, but might want to add a little diode action in the mix. Prices are pretty much the same. Thanks.
