djrams80 Was gracious enough while he was up here in Oregon to test the jammer setup on the Jeep. I was highly impressed with the performance of the ZR4. It was JTG on CM, and down to 25' with headlight shots. Thanks DJ for helping out and volunteering to shoot us with your gun! Anyone on the fence about the ZR4, I would not hesitate to buy one. If it provided JTG on this bread box Jeep Grand Cherokee, I would not hesitate installing it on something that has a lower profile than my rig and expect stellar protection in ALL real world situations. Thanks DJ for everything!
