These things are amazing... my friends are like "what the heck, those are so cool". I leave the passenger one in all the time, and the drivers goes in when I won't be on the road a lot. They are very quiet with wind even at freeway speeds. If you need to roll the window down they can be a little tricky to get back in place/aligned but not bad (sometimes window hits edge instead of going between gap where it should). They keep rain, bugs, thieves out and let ventilation happen... I even washed my van with them in without water getting inside.

Almost a necessity in a hot climate
These vents work great. I have a set of cab area sunshields that I use along with the vents. These two measures plus running the fan on low do quite a bit to keep the interior temp reasonable when parked or boondocking.

Living in Georgia the heat build up when parked in driveway can be quite intense. I leave these in place, no rain gets in but the heat escapes. Using the fan with the vents when occupied works wonderfully, no bugs and no rain. Perfect solution.
