I love it!!! It's a lot quieter than the V1 I used to have, and the sucker I got this off of did a straight trade!!!
I found on a Cobra forum that you're supposed to point them 45 degrees up, but the BEST angle is 38.2 degrees if you want to get the best reception. One of the Cobra Engineers told me that, so I thought I would pass it along.
It also gives me VG and Safety alerts; I encourage everyone to look into this. Cobra FTW!!!!
