You know I have been thinking how good the Blinder M25 J15 really did. Without looking at the past number in deep detail I believe the Blinder M25 J15 did better than Blinder M40 (past GOL tests). I could only imagine how a Blinder M45 J15 would have done at GOL 2008. Either way I walked away so impressed that my Wife's SUV will have a BLinder M45 J15 installed! Do not get me wrong I LOVE the LI but one thing that I LOVE about Blinder is its solid past track record for quality. Not only that but it has saved my family over a dozen LIDAR tickets. Torbin Do not mess too much with this J15.
