From what I've read...those that have it, love it. However, you can find a comparable system with something like the passport escort 9500ix, which also has gps. The downside to both is that they are pretty expensive.
I personally don't have one, so I can't give my own take on this. But I will say that if you get one, don't get lazy. Always depend on your eyes as your first "detector" since some officers use a laser which the radars don't detect until you're caught...
