Personally, I'm using the 9500ix and it has saved me a handful of times. Still need to hardwire a power source though, I've been dealing with the dangling power cord so far.
I also went with the 9500ix the range is similar to the V1 but the 9500ix has a built in GPS so it learns your regular routes and do not go off for all those gas stations and stores. I prefer to only hear the detector when its really a cop. So if my detector goes off anytime in my area or on my way to work then I know its a cop.
