To be honest with you, despite the concerns expressed by some about the ZR4's "performance" relative to other jammers, it is its performance in the real-world against the average officer targeting.
I have had terrific real-world results with my 9500ci coupled with Veil G4 on my difficult to cloak metallic silver large sedan and have more than adequate protection.
I have even had some rear targeting in Kentucky that provided real-world protection (and I am sure I would have been toast without it).
I am personally not measuring my satisfaction with my particular laser jammer by its percentage of JTG (or lack thereof) and I have yet to encounter a real-world laser encounter where I did not have the protection I needed. Until such time otherwise, that's good enough for me.
This in no way takes away my support for these other jammmers and the enthusiasms shared by users of them.
It's all good.
