I've had these on for a while now and I must say I enjoy them. Not worried about leaving my windows cracked and inviting opportunistic thieves, letting all the hot air out, worrying about rain. Now granted, if someone wants in they will get in period, but you can't want what you don't know is there so the dark color masks the fact that the windows are slightly down from all but the up close look so I'm not advocating this as a theft deterrent device. Just a deterrent for the opportunistic person who might see the opening and try to reach in and help themselves.
For in In-Channel model the price wasn't much more than others and I didn't want to use the ones that stick on the outside. My chief complaint is they do affect visibility, but I assume all brands would at some point. Its not horrible but the curve of the visors do distort light a bit and add to existing blind spots.
I'll get some pic's up shortly. Probably the same time I get pictures of the stock and locking version of the Yakima mounts. :-/ Pictures are taken I just need to put them up.
