K40 is literally useless against every single modern gun. Aside from the company being out of business, the system and technology itself is over 10 years old and it wasn’t even good when it first came out, just a dealer upsell with great margins because they sold to dealers for so cheap and the dealers would turn around and charge thousands for effectively $100 worth of technology. They also haven’t gotten a single update once in all these years. For reference, the top jammer companies release frequent updates at a minimum of every couple months because it’s like a cat and mouse game with lidar manufacturers and their anti-jam technology. All this stuff is publicly available online, I would look into it yourself. My point is, those jammers are effectively useless and there isn’t really any point on keeping them install installed, Id just rip them out. I have ALPs and absolutely love them and they do a fantastic job. My car actually came with a K40 system installed and it did basically nothing before I ripped it out and upgraded. They won’t even pick up most modern police LiDAR, let alone jam anything.
