I must say, this is a really nice piece. I had no interest in the etched or lighted unit but really wanted a wind blocker for my car. My first thought was that this unit is rather expensive but after looking at a few others it just seemed like the most sensible mounting system and the reviews were pretty darn good all around. So I pulled the trigger and bought one - it arrived on Saturday. Wow, am I impressed!! Installation was a snap and, even though I was sure it would rattle at least a little, so far it hasn't made a peep! And with my rearview mirror adjusted the way it is I don't even see the top edge of the thing, so from that perspective it's as if it isn't even there, so good is the optical quality of the material. Oh, and it does a great job reducing turbulence in the cockpit. I highly recommend it.
