The Radenso/ALP system is the only one that can defend against all the laser guns you might encounter on the road, like DragonEye. The difficult-to-jam guns with ECCM like DragonEye aren't in super widespread use, but if you live in an area where they're used, you're gonna want an ALP system.
If memory serves, the Radenso RC-M Ultimate is around the same price as similar offerings from companies like Escort and K40, and you know you have all your bases covered with the Radenso system.
