I received my Redline on Friday and I have driven about 100miles with it (unfortunately I have not seen any LEOs!). I ran it past all the usual K-band speed signs and it seems be beat my STi on all of them.
My initial impression of the Redline's over the hill performance (on some speed signs) is better than my STi. It alerts 200-400 feet earlier than the STi, I need to do more runs though to see if this is consistent.
The Redline also seems to false less than my STi, All the usual places my STi falses the Redline does not (most of the time).
I will try to get some cockpit videos soon and post them when I have some real threats.
So far I enjoy the Redline, I will be keeping it because I do a lot of VA driving, then the girlfriend can get the STi back, so she will be happy about that!
Interesting Note: I know it is generally frowned upon to run 2 detectors together but when I run the STi and Redline together I seem to get different frequencies from each detector for the same speed signs.
